dividend over the divisor
“a divided by b”, “a by b” or “a over b”.
dividend is divided by the divisor to get a quotient.

Example:
20 ÷ 5 = 4
20 is the dividend,
5 is the divisor,
4 is the quotient.

In some cases, the divisor may not be contained fully by the dividend
Example, 10 ÷ 3 leaves a remainder of one
1 is the remainder
