Let us check if our division is correct.

divisor × quotient + remainder = 45 × 16268 + 33

= 732060 + 33

= 732093 = dividend

Hence division is correct.

Division by a Three Digit Number

In the same way a number can be divided by a three digit number.

Example 4: 678523 ÷ 427

Solution: 1 5 8 9

427 6 7 8 5 2 3
– 4 2 7
2 5 1 5

– 2 1 3 5
3 8 0 2
– 3 4 1 6

3 8 6 3
– 3 8 4 3
2 0 Q = 1589, R = 20

Let us check if our division is correct.

divisor × quotient + remainder = 427 × 1589 + 20

= 678503 + 20

= 678523 = dividend

Hence division is correct.
