Remainders after division by 2-4

Remainder after division

The result of division is not always a nice and round number, e.g. 7÷3. We know that three fits twice into 7. However, 3×2=6. There is 1 still remaining. We call 1 in this case the remainder or left over after dividing (7 is dividend and 3 is divisor).

To calculate it you need to find the greatest multiple of the divisor which is still lower than the dividend and subtract it from dividend.

Example:
44÷5 → 5×8=40 → 44−40=4 (4 is remainder after division by 5: 44=5×8+4).
