As we know, division consists in dividing a certain value or amount into groups of equal values. With long division, the values ​​are divided individually at each digit (thousands, hundreds, tens, ones), starting with the highest digit.

Division by a single-digit divisor

1. Divide 27 by 9

Solution:

Let’s share.

Step I: Write 27 in the bracket and 9 on the left side of the bracket.

Step II: Start by dividing from left to right i.e. divide 2 by 9. Since we can’t divide 2 by 9, we are going to divide 27 by 9.

Step III: Remember the table from 9.

9 × 3 = 27

Now write 3 in the quotient and subtract 27 from 27. The result is 0.

So 27 ÷ 9 = 3

2. Divide 92 by 4

Solution:

Let’s share.

Step I: Write 92 in the bracket and 4 on the left side of the bracket.

Step II: Start by dividing from left to right, that is, divide 9 tens by 4.

4 × 2 = 8

4 × 3 = 12

12 tens are greater than 9 tens, so let’s take 4 × 2 = 8 tens.

Step III: Write 2 in the quotient.

Step IV: Subtract 8 from 9 and get 1 as the remainder.

Step V: Drag 2 down from your place and write it to the right of 1.

12 is the new dividend.

Step VI: Write 3 in the quotient and subtract 12 from 12. The result is 0.

So 92 ÷ 4 = 23

3. Find the quotient and the remainder of 649 ÷ 9.

Solution:

Step I: We’ll start dividing the hundreds first. Since 6 hundreds cannot be divided into 9 hundreds groups, the quotient in the hundreds column is zero.

Step II: 6 hundreds are now converted to 60 tens and added to 4 tens, making 64 tens.

Step III: 64 tens result in 9 groups of 7 tens each and 1 tens is left over.

Step IV: 1 Ten equals 10 ones, 10 ones + 9 ones = 19 ones

Step V: 19 ones can be divided into 2 groups of 9 and 1 of them is left over.

Long division

q = 72; r = 1

Division by two-digit divisors

4th Divide 2698 by 21.

Solution:

Do you remember the process of long division.

Step I: 2 thousand cannot be divided into groups of 21 thousand. So 0 is put in the thousands column as a quotient.

Step II: 2 thousand makes 20 hundred.

20 hundreds + 6 hundreds equals 26 hundreds. 26 hundreds make a group of 21 hundreds. 5 hundred are left.

Step III: 5 hundreds equals 50 tens.

Long division by two-digit divisors

q = 128; r = 10

So, 50 tens + 9 tens = 59 tens

59 tens are divided into 21 groups of ten

59 tens ÷ 21 results in 2 groups with 17 tens left.

2 is placed in the quotient in the tens column.

Step IV: 17 tens = 170 ones

170 ones + 8 ones = 178 ones

178 ones makes 21 results in 8 groups with 10 ones left.

If we divide 2,698 by 21, we get 128 as the quotient and 10 as the remainder.

Word problems with long division:

To solve any word problem, we need to carefully read each word and carefully choose numbers from the question to solve.

5. If 60 biscuits are to be packed in 5 packages, how many biscuits are to be packed in one package?

Solution:

Number of cookies = 60 cookies

Distributed equally in 5 packets

Number of cookies in a package = 60 ÷ 5

Word problem on Long Division Math

Thus, 12 biscuits are packed in one package.
