How to divide decimal fractions by natural numbers? Consider the rule and its application with examples.

To divide a decimal by a natural number, you need:

1) divide the decimal fraction by the number, ignoring the comma;

2) when the division of the integer part is over, put a comma in the private part.

Examples.

Split decimals:

To divide a decimal by a natural number, divide without paying attention to the comma. 5 is not divisible by 6, so we put zero in the quotient. The division of the integer part is over, in the private we put a comma. We take zero. Divide 50 by 6. Take 8 each. 6∙8=48. From 50 we subtract 48, in the remainder we get 2. We demolish 4. We divide 24 by 6. We get 4. The remainder is zero, which means the division is over: 5.04: 6 = 0.84.

2) 19,26: 18

We divide the decimal fraction by a natural number, ignoring the comma. We divide 19 by 18. We take 1 each. The division of the integer part is over, in the private we put a comma. We subtract 18 from 19. The remainder is 1. We demolish 2. 12 is not divisible by 18, in private we write zero. We demolish 6. 126 divided by 18, we get 7. The division is over: 19.26: 18 = 1.07.

Divide 86 by 25. Take 3 each. 25∙3=75. We subtract 75 from 86. The remainder is 11. The division of the integer part is over, in the private we put a comma. Demolish 5. Take 4 each. 25∙4=100. Subtract 100 from 115. The remainder is 15. We demolish zero. We divide 150 by 25. We get 6. The division is over: 86.5: 25 = 3.46.

4) 0,1547: 17

Zero is not divisible by 17, we write zero in private. The division of the integer part is over, in the private we put a comma. We demolish 1. 1 is not divisible by 17, we write zero in private. We demolish 5. 15 is not divisible by 17, in private we write zero. Demolish 4. Divide 154 by 17. Take 9 each. 17∙9=153. We subtract 153 from 154. The remainder is 1. We take down 7. We divide 17 by 17. We get 1. The division is over: 0.1547: 17 = 0.0091.

5) A decimal fraction can also be obtained by dividing two natural numbers.

When dividing 17 by 4, we take 4 each. The division of the integer part is over, in the private we put a comma. 4∙4=16. We subtract 16 from 17. The remainder is 1. We demolish zero. Divide 10 by 4. Take 2 each. 4∙2=8. We subtract 8 from 10. The remainder is 2. We demolish zero. We divide 20 by 4. We take 5 each. The division is over: 17: 4 \u003d 4.25.

And a couple more examples for dividing decimal fractions by natural numbers:

At school, these actions are studied from simple to complex. Therefore, it is absolutely necessary to master well the algorithm for performing these operations on simple examples. So that later there will be no difficulties with dividing decimal fractions into a column. After all, this is the most difficult version of such tasks.

This subject requires consistent study. Gaps in knowledge are unacceptable here. This principle should be learned by every student already in the first grade. Therefore, if you skip several lessons in a row, you will have to master the material yourself. Otherwise, later there will be problems not only with mathematics, but also with other subjects related to it.

Second required condition successful study mathematics - move on to examples for division in a column only after addition, subtraction and multiplication have been mastered.

It will be difficult for a child to divide if he has not learned the multiplication table. By the way, it is better to learn it from the Pythagorean table. There is nothing superfluous, and multiplication is easier to digest in this case.

How are natural numbers multiplied in a column?

If there is a difficulty in solving examples in a column for division and multiplication, then it is necessary to start solving the problem with multiplication. Because division is the inverse of multiplication:

  1. Before multiplying two numbers, you need to look at them carefully. Choose the one with more digits (longer), write it down first. Place the second one under it. Moreover, the numbers of the corresponding category should be under the same category. That is, the rightmost digit of the first number must be above the rightmost digit of the second.
  2. Multiply the rightmost digit of the bottom number by each digit of the top number, starting from the right. Write the answer under the line so that its last digit is under the one by which it was multiplied.
  3. Repeat the same with the other digit of the bottom number. But the result of the multiplication must be shifted one digit to the left. In this case, its last digit will be under the one by which it was multiplied.

Continue this multiplication in a column until the numbers in the second multiplier run out. Now they need to be folded. This will be the desired answer.

Algorithm for multiplying into a column of decimal fractions

First, it is supposed to imagine that not decimal fractions are given, but natural ones. That is, remove commas from them and then proceed as described in the previous case.

The difference begins when the answer is written. At this point, it is necessary to count all the numbers that are after the decimal points in both fractions. That is how many of them you need to count from the end of the answer and put a comma there.

It is convenient to illustrate this algorithm with an example: 0.25 x 0.33:

How to start learning to divide?

Before solving examples for division in a column, it is supposed to remember the names of the numbers that are in the example for division. The first of them (the one that divides) is the divisible. The second (divided by it) is a divisor. The answer is private.

After that, using a simple everyday example, we will explain the essence of this mathematical operation. For example, if you take 10 sweets, then it is easy to divide them equally between mom and dad. But what if you need to distribute them to your parents and brother?

After that, you can get acquainted with the rules of division and master them on concrete examples. Simple ones at first, and then moving on to more and more complex ones.

Algorithm for dividing numbers into a column

First, we present the procedure for natural numbers that are divisible by a single-digit number. They will also be the basis for multi-digit divisors or decimal fractions. Only then it is supposed to make small changes, but more on that later:

  • Before doing division in a column, you need to find out where the dividend and divisor are.
  • Write down the dividend. To the right of it is a divider.
  • Draw a corner on the left and bottom near the last corner.
  • Determine the incomplete dividend, that is, the number that will be the minimum for division. Usually it consists of one digit, maximum of two.
  • Choose the number that will be written first in the answer. It must be the number of times the divisor fits in the dividend.
  • Write down the result of multiplying this number by a divisor.
  • Write it under an incomplete divisor. Perform subtraction.
  • Carry to the remainder the first digit after the part that has already been divided.
  • Again choose the number for the answer.
  • Repeat multiplication and subtraction. If the remainder zero and the dividend is over, then the example is done. Otherwise, repeat the steps: demolish the number, pick up the number, multiply, subtract.

How to solve long division if there is more than one digit in the divisor?

The algorithm itself completely coincides with what was described above. The difference will be the number of digits in the incomplete dividend. Now there should be at least two of them, but if they turn out to be less than the divisor, then it is supposed to work with the first three digits.

There is another nuance in this division. The fact is that the remainder and the figure carried to it are sometimes not divisible by a divisor. Then it is supposed to attribute one more figure in order. But at the same time, the answer must be zero. If three-digit numbers are divided into a column, then more than two digits may need to be demolished. Then the rule is introduced: zeros in the answer should be one less than the number of digits taken down.

You can consider such a division using the example - 12082: 863.

  • The incomplete divisible in it is the number 1208. The number 863 is placed in it only once. Therefore, in response, it is supposed to put 1, and write 863 under 1208.
  • After subtraction, the remainder is 345.
  • To him you need to demolish the number 2.
  • In the number 3452, 863 fits four times.
  • Four must be written in response. Moreover, when multiplied by 4, this number is obtained.
  • The remainder after subtraction is zero. That is, the division is completed.

The answer in the example is 14.

What if the dividend ends in zero?

Or a few zeros? In this case, a zero remainder is obtained, and there are still zeros in the dividend. Do not despair, everything is easier than it might seem. It is enough just to attribute to the answer all the zeros that remained undivided.

For example, you need to divide 400 by 5. The incomplete dividend is 40. Five is placed in it 8 times. This means that the answer is supposed to be written 8. When subtracting, there is no remainder. That is, the division is over, but zero remains in the dividend. It will have to be added to the answer. Thus, dividing 400 by 5 gives 80.

What if you need to divide a decimal?

Again, this number looks like a natural number, if not for the comma separating the integer part from the fractional part. This suggests that the division of decimal fractions into a column is similar to the one described above.

The only difference will be the semicolon. It is supposed to be answered immediately, as soon as the first digit from the fractional part is taken down. In another way, it can be said like this: the division of the integer part has ended - put a comma and continue the solution further.

When solving examples for dividing into a column with decimal fractions, you need to remember that any number of zeros can be assigned to the part after the decimal point. Sometimes this is necessary in order to complete the numbers to the end.

Division of two decimals

It may seem complicated. But only at the beginning. After all, how to perform division in a column of fractions by a natural number is already clear. So, we need to reduce this example to the already familiar form.

Make it easy. You need to multiply both fractions by 10, 100, 1,000, or 10,000, or maybe a million if the task requires it. The multiplier is supposed to be chosen based on how many zeros are in the decimal part of the divisor. That is, as a result, it turns out that you will have to divide a fraction by a natural number.

And it will be in the worst case. After all, it may turn out that the dividend from this operation becomes an integer. Then the solution of the example with division into a column of fractions will be reduced to simple option: operations with natural numbers.

As an example: 28.4 divided by 3.2:

  • First, they must be multiplied by 10, since in the second number there is only one digit after the decimal point. Multiplying will give 284 and 32.
  • They are supposed to be divided. And at once the whole number is 284 by 32.
  • The first matched number for the answer is 8. Multiplying it gives 256. The remainder is 28.
  • The division of the integer part is over, and a comma is supposed to be put in the answer.
  • Demolish to remainder 0.
  • Take 8 again.
  • Remainder: 24. Add another 0 to it.
  • Now you need to take 7.
  • The result of the multiplication is 224, the remainder is 16.
  • Demolish another 0. Take 5 and get exactly 160. The remainder is 0.

Division completed. The result of the 28.4:3.2 example is 8.875.

What if the divisor is 10, 100, 0.1, or 0.01?

As with multiplication, long division is not needed here. It is enough just to move the comma in the right direction for a certain number of digits. Moreover, according to this principle, you can solve examples with both integers and decimal fractions.

So, if you need to divide by 10, 100 or 1000, then the comma is moved to the left by as many digits as there are zeros in the divisor. That is, when a number is divisible by 100, the comma should move to the left by two digits. If the dividend is a natural number, then it is assumed that the comma is at the end of it.

This action produces the same result as if the number were to be multiplied by 0.1, 0.01, or 0.001. In these examples, the comma is also moved to the left by a number of digits equal to the length of the fractional part.

When dividing by 0.1 (etc.) or multiplying by 10 (etc.), the comma should move to the right by one digit (or two, three, depending on the number of zeros or the length of the fractional part).

It is worth noting that the number of digits given in the dividend may not be sufficient. Then the missing zeros can be assigned to the left (in the integer part) or to the right (after the decimal point).

Division of periodic fractions

In this case, you will not be able to get the exact answer when dividing into a column. How to solve an example if a fraction with a period is encountered? Here it is necessary to move on to ordinary fractions. And then perform their division according to the previously studied rules.

For example, you need to divide 0, (3) by 0.6. The first fraction is periodic. It is converted to the fraction 3/9, which after reduction will give 1/3. The second fraction is the final decimal. It is even easier to write down an ordinary one: 6/10, which is equal to 3/5. The rule for dividing ordinary fractions prescribes to replace division with multiplication and the divisor with the reciprocal of a number. That is, the example boils down to multiplying 1/3 by 5/3. The answer is 5/9.

If the example has different fractions...

Then there are several possible solutions. First of all, common fraction You can try to convert to decimal. Then divide already two decimals according to the above algorithm.

Secondly, each finite decimal can be written in the form of an ordinary It's just not always convenient. Most often, such fractions turn out to be huge. Yes, and the answers are cumbersome. Therefore, the first approach is considered more preferable.

Column division is an integral part of the school curriculum and necessary knowledge for the child. To avoid problems in the lessons and with their implementation, it is necessary to give the child basic knowledge from a young age.

It is much easier to explain to a child certain things and processes in game form, and not in the format of a standard lesson (although today there are quite a variety of teaching methods in different forms).

From this article you will learn

The principle of division for kids

Children constantly come across different mathematical terms, without even suspecting where they come from. Indeed, many mothers, in the form of a game, explain to the child that dads are more of a plate, go further to the kindergarten than to the store and other simple examples. All this gives the child an initial impression of mathematics, even before the child goes to first grade.

To teach a child to divide without a remainder, and later with a remainder, it is necessary to directly invite the child to play division games. Divide, for example, sweets among themselves, and then add the following participants in turn.

First, the child will share candy, giving each participant one. And at the end, draw a conclusion together. It should be clarified that "sharing" means the same number of candies for everyone.

If you need to explain this process using numbers, then you can give an example in the form of a game. We can say that the number is candy. It should be explained that the number of sweets to be divided between the participants is divisible. And the number of people into whom these sweets are divided is a divisor.

Then you should show it all clearly, give “live” examples in order to quickly teach the crumbs to divide. Playing, he will understand and learn everything much faster. While the algorithm will be difficult to explain, and now it is not necessary.

How to teach your baby to divide in a column

Explaining math to a little bit is a good preparation for going to class, especially math class. If you decide to move on to teaching your child to divide by a column, then he has already learned such actions as addition, subtraction, and what the multiplication table is.

If this still causes some difficulties for him, then all this knowledge needs to be tightened up. It is worth recalling the algorithm of actions of previous processes, teaching how to freely use your knowledge. Otherwise, the baby will simply get confused in all processes, and will cease to understand anything.

To make this easier to understand, there is now a division table for toddlers. The principle is the same as for multiplication tables. But is such a table already needed if the baby knows the multiplication table? It depends on the school and the teacher.

When forming the concept of “division”, it is necessary to do everything in a playful way, give all examples on things and objects familiar to the child.

It is very important that all items be of an even number, so that it is clear to the baby that the result is equal parts. This will be correct, because it will allow the baby to realize that division is the reverse process of multiplication. If the items are an odd number, then the result will come out with the remainder and the baby will get confused.

Multiply and divide using a spreadsheet

When explaining to the baby the relationship between multiplication and division, it is necessary to clearly show all this using some example. For example: 5 x 3 = 15. Remember that the result of multiplication is the product of two numbers.

And only after that, explain that this is the reverse process to multiplication and demonstrate this clearly using a table.

Say that you need to divide the result “15” by one of the factors (“5” / “3”), and the result will be a constantly different factor that did not take part in the division.

It is also necessary to explain to the baby how the categories that perform division are correctly called: dividend, divisor, quotient. Again, use an example to show which of these is a particular category.

Dividing by a column is not a very complicated thing, it has its own easy algorithm that the baby needs to be taught. After fixing all these concepts and knowledge, you can proceed to further training.

In principle, parents should learn the multiplication table with their beloved child in reverse order, and memorize it by heart, as it will be necessary when learning to divide by a column.

This must be done before going to first grade, so that it is much easier for a child to get used to school and keep up with school curriculum, and so that the class, due to small mishaps, does not begin to tease the child. The multiplication table is both at school and in notebooks, so you don’t have to carry a separate table to school.

Divide with a column

Before starting the lesson, you need to remember the names of the numbers when dividing. What is a divisor, dividend and quotient. The child must divide these numbers into the correct categories without errors.

The most important thing when learning division by a column is to learn the algorithm, which, in general, is quite simple. But first, explain to the child the meaning of the word "algorithm" if he has forgotten it or has not studied it before.

In the event that the baby is well versed in the multiplication table and inverse division, he will not have any difficulties.

However, it is impossible to linger on the result obtained for a long time; it is necessary to regularly train the acquired skills and abilities. Move on as soon as it becomes clear that the baby understood the principle of the method.

It is necessary to teach the baby to divide in a column without a remainder and with a remainder, so that the child is not afraid that he failed to divide something correctly.

To make it easier to teach the baby the process of division, you must:

  • in 2-3 years, understanding the whole-part relationship.
  • at 6-7 years old, the baby should be able to freely perform addition, subtraction and be aware of the essence of multiplication and division.

It is necessary to encourage the child’s interest in mathematical processes so that this lesson at school brings him pleasure and a desire to learn, and not motivate him only in the classroom, but also in life.

The child should carry different tools for math lessons, learn how to use them. However, if it is difficult for a child to carry everything, then do not overload it.

A column calculator for Android devices will be a great helper for modern schoolchildren. The program not only gives the correct answer to mathematical action, but also clearly demonstrates its step-by-step solution. If you need more complex calculators, you can look at the advanced engineering calculator.

Peculiarities

The main feature of the program is the uniqueness of the calculation of mathematical operations. Displaying the calculation process in a column allows students to get acquainted with it in more detail, understand the solution algorithm, and not just get the finished result and rewrite it in a notebook. This feature has a huge advantage over other calculators. quite often at school, teachers require intermediate calculations to be written down to make sure that the student does them in his mind and really understands the algorithm for solving problems. By the way, we have another program of a similar kind - .

To start using the program, you need to download a calculator in a column on Android. You can do this on our website absolutely free of charge without additional registrations and SMS. After installation will open main page in the form of a notebook sheet in a cell, on which, in fact, the results of calculations and their detailed solution. At the bottom there is a panel with buttons:

  1. Numbers.
  2. Signs of arithmetic operations.
  3. Delete previously entered characters.

Input is carried out according to the same principle as on. All the difference is only in the interface of the application - all mathematical calculations and their results are displayed in a virtual student notebook.

The application allows you to quickly and correctly perform standard mathematical calculations for a student in a column:

  • multiplication;
  • division;
  • addition;
  • subtraction.

A nice addition to the app is the daily reminder function. homework mathematics. If you want, do your homework. To enable it, go to the settings (press the button in the form of a gear) and check the reminder box.

Advantages and disadvantages

  1. It helps the student not only to quickly get the correct result of mathematical calculations, but also to understand the very principle of calculation.
  2. Very simple, intuitive interface for every user.
  3. You can install the application even on the most budget Android device with operating system 2.2 and later.
  4. The calculator saves a history of mathematical calculations, which can be cleared at any time.

The calculator is limited in mathematical operations, so it will not work for complex calculations that an engineering calculator could handle. However, given the purpose of the application itself - to clearly demonstrate to elementary school students the principle of calculating in a column, this should not be considered a disadvantage.

The application will also be an excellent assistant not only for schoolchildren, but also for parents who want to get their child interested in mathematics and teach him how to correctly and consistently perform calculations. If you have already used the Stacked Calculator app, leave your impressions below in the comments.

Division is one of the four basic mathematical operations (addition, subtraction, multiplication). Division, like other operations, is important not only in mathematics, but also in Everyday life. For example, you will hand over the money with a whole class (25 people) and buy a gift for the teacher, but you will not spend everything, there will be change. So you will have to share the change among all. The division operation comes into play to help you solve this problem.

Division is an interesting operation, as we will see with you in this article!

Number division

So, a little theory, and then practice! What is division? Division is breaking something into equal parts. That is, it can be a package of sweets that needs to be divided into equal parts. For example, there are 9 sweets in a bag, and the person who wants to receive them has three. Then you need to divide these 9 sweets into three people.

It is written like this: 9:3, the answer will be the number 3. That is, dividing the number 9 by the number 3 shows the number of numbers three contained in the number 9. The reverse action, the test, will be multiplication. 3*3=9. Right? Absolutely.

So, consider the example of 12:6. First, let's name each component of the example. 12 - divisible, that is. number that is divisible. 6 - divisor, this is the number of parts into which the dividend is divided. And the result will be a number called "private".

Divide 12 by 6, the answer will be the number 2. You can check the solution by multiplying: 2*6=12. It turns out that the number 6 is contained 2 times in the number 12.

Division with remainder

What is division with remainder? This is the same division, only the result is not an even number, as shown above.

For example, let's divide 17 by 5. Since the largest number divisible by 5 to 17 is 15, the answer is 3 and the remainder is 2, and is written like this: 17:5=3(2).

For example, 22:7. In the same way, we determine the maximum number divisible by 7 to 22. This number is 21. Then the answer will be: 3 and the remainder 1. And it is written: 22:7=3(1).

Division by 3 and 9

A special case of division is division by the number 3 and the number 9. If you want to know whether a number is divisible by 3 or 9 without a remainder, then you will need:

    Find the sum of the digits of the dividend.

    Divide by 3 or 9 (depending on what you need).

    If the answer is obtained without a remainder, then the number will be divided without a remainder.

For example, the number 18. The sum of the digits 1+8 = 9. The sum of the digits is divisible by both 3 and 9. The number 18:9=2, 18:3=6. Divided without a trace.

For example, the number 63. The sum of the digits 6+3 = 9. Divisible by both 9 and 3. 63:9=7, and 63:3=21. Such operations are carried out with any number to find out if it is divisible with the remainder 3 or 9 or not.

Multiplication and division

Multiplication and division are opposite operations. Multiplication can be used as a division test, and division as a multiplication test. You can learn more about multiplication and master the operation in our article about multiplication. In which multiplication is described in detail and how to perform it correctly. There you will also find the multiplication table and examples for training.

Here is an example of checking division and multiplication. Let's say an example is 6*4. Answer: 24. Then let's check the answer by division: 24:4=6, 24:6=4. Decided right. In this case, the check is made by dividing the answer by one of the factors.

Or an example is given for dividing 56:8. Answer: 7. Then the test will be 8*7=56. Right? Yes. In this case, the check is made by multiplying the answer by the divisor.

Division 3 class

In the third grade, division is just beginning to pass. Therefore, third-graders solve the simplest problems:

Task 1. A factory worker was given the task of putting 56 cakes into 8 packages. How many cakes must be put in each package to get the same amount in each?

Task 2. On New Year's Eve, the school gave out 75 sweets to children in a class of 15 students. How many candies should each child get?

Task 3. Roma, Sasha and Misha picked 27 apples from the apple tree. How many apples will each get if they need to be divided equally?

Task 4. Four friends bought 58 cookies. But then they realized that they could not divide them equally. How many cookies do you need to buy for each child to get 15 cookies?

Division 4 class

Division in the fourth grade is more serious than in the third. All calculations are carried out by dividing into a column, and the numbers that participate in the division are not small. What is division into a column? You can find the answer below:

Long division

What is division into a column? This is a method that allows you to find the answer to the division big numbers. If a prime numbers like 16 and 4, can be divided, and the answer is clear - 4. That 512:8 in the mind is not easy for a child. And to tell about the technique for solving such examples is our task.

Consider the example, 512:8.

1 step. We write the dividend and the divisor as follows:

The quotient will be written as a result under the divisor, and the calculations under the dividend.

2 step. The division starts from left to right. Let's take number 5 first.

3 step. The number 5 is less than the number 8, which means that it will not be possible to divide. Therefore, we take one more digit of the dividend:

Now 51 is greater than 8. This is an incomplete quotient.

4 step. We put a dot under the divider.

5 step. After 51 there is another number 2, which means that the answer will have one more number, that is. quotient is a two-digit number. We put the second point:

6 step. We begin the division operation. Largest number, divisible without a remainder by 8 to 51 - 48. Dividing 48 by 8, we get 6. We write the number 6 instead of the first point under the divisor:

7 step. Then we write the number exactly under the number 51 and put the "-" sign:

8 step. Then subtract 48 from 51 and get the answer 3.

* 9 step*. We demolish the number 2 and write next to the number 3:

10 step The resulting number 32 is divided by 8 and we get the second digit of the answer - 4.

So, the answer is 64, without a trace. If we divided the number 513, then the remainder would be one.

Three-digit division

The division of three-digit numbers is performed using the long division method, which was explained using the example above. An example of just the same three-digit number.

Division of fractions

Dividing fractions is not as difficult as it seems at first glance. For example, (2/3):(1/4). The division method is quite simple. 2/3 is the dividend, 1/4 is the divisor. You can replace the division sign (:) with multiplication ( ), but for this you need to swap the numerator and denominator of the divisor. That is, we get: (2/3)(4/1), (2/3) * 4, this is equal to - 8/3 or 2 integers and 2/3. Let's give another example, with an illustration for a better understanding. Consider fractions (4/7):(2/5):

As in the previous example, we flip the divisor 2/5 and get 5/2, replacing division with multiplication. We get then (4/7)*(5/2). We make a reduction and answer: 10/7, then we take out the whole part: 1 whole and 3/7.

Dividing a Number into Classes

Let's imagine the number 148951784296, and divide it by three digits: 148 951 784 296. So, from right to left: 296 is the class of units, 784 is the class of thousands, 951 is the class of millions, 148 is the class of billions. In turn, in each class 3 digits have their own category. From right to left: the first digit is units, the second digit is tens, the third is hundreds. For example, the class of units is 296, 6 is units, 9 is tens, 2 is hundreds.

Division of natural numbers

Division of natural numbers is the simplest division described in this article. It can be both with a remainder and without a remainder. The divisor and dividend can be any non-fractional, whole numbers.
