A "quotient" is the result of a division problem. For example: For 6/3, "2" is the quotient, 6 is the dividend, and 3 is the divisor.
Sometime when dividing, there is something left over, it is called the remainder. For example: For 7/3, "2" is the quotient, 7 is the dividend, 3 is the divisor, and "1" is the remainder. 7/3 = 2 R 1.
dividend = divisor * quotient + remainder
For example:
7 = 3 * 2 + 1
