One number does not always divide another evenly. Then there is a remainder. For example, you cannot split 17 apples equally among 5 plates: each plate gets 3 apples and 2 are left over. We write: 17÷5=3 R 2 (read “3 remainder 2”). Important: the remainder is always less than the divisor (r<b).
a÷b=c R r with r<b
Example: 20÷6=3 R 2
The remainder cannot be greater than or equal to the divisor
