CHECkinG DiviSion

Division can be checked by the following method.
Quotient × Divisor + Remainder = Dividend

Example. Check whether the following division is correct.
9 Quotient

Divisor 5 4 8 Dividend
– 4 5 Keep in Mind
3 Remainder The remainder is always

Solution. Let us find: smaller than the divisor.
Quotient × Divisor + Remainder = Dividend

9 × 5 + 3 = 48
"When a number is
45 + 3 = 48 divided by 1, the quotient
48 = 48 is the number itself".

Thus, the division is correct.
