How to compute 36 divided by 21?

Division is a mathematical operation that consists of determining how many times a number (the divisor, 36) is contained in another number (the dividend, 21). The result of this operation is called the quotient.

Asking for the quotient of 36 and 21 is the same of getting the result of 36 divided by 21, which can be displayed in several ways:

Floating point number 1.7142857142857
Rational number 12/7
Mixed number 1 5/7
Euclidean division 1 remainder 15
Integer quotient 1

36 divided by 21, step by step

Step 1

Set up the division: position the divisor (21) on the left and the dividend (36) on the right.

2 1 ) 3 6

Step 2

Determine how many times 21 can be multiplied without exceeding the dividend (3). The answer is 0. Place this digit on top.

0
2 1 ) 3 6

Step 3

Multiply the divisor by the previous result (21 × 0 = 0). Write the new result below the dividend.

0
2 1 ) 3 6
0

Step 4

Subtract this result from the number above it (3 - 0 = 3). Write the difference below.

0
2 1 ) 3 6
- 0
3

Step 5

Bring down the next digit of the dividend (6) down.

0
2 1 ) 3 6
- 0
3 6

Step 6

Determine how many times 21 can be multiplied without exceeding the dividend (36). The answer is 1. Place this digit on top.

0 1
2 1 ) 3 6
- 0
3 6

Step 7

Multiply the divisor by the previous result (21 × 1 = 21). Write the new result below the dividend.

0 1
2 1 ) 3 6
- 0
3 6
2 1

Step 8

Subtract this result from the number above it (36 - 21 = 5). Write the difference below.

0 1
2 1 ) 3 6
- 0
3 6
- 2 1
1 5

There are no more digits left to go down from the dividend, indicating that the long division is complete. The quotient is the number at the very top, and any remainder is found at the bottom.

Thus, for 36 divided by 21, the solution is: 1 remainder 15.
