A dividend is is a number to be divided and a divisor is a number to be divided into a dividend. Here the dividend is a three digit number and is divided by a one digit divisor. The quotient or result is a two digit number as stated. So in math terms, we can state that the dividend is a three digit number and that the divisor is a one digit number.

Mental math like if 12 into 72 it will not be a double digit if you divide 100 by 10 it will be double digits. Most times if you have a tripple digit number and divide it by double digit the answer will be a double digit.
