The concept of "quotient" in primary school mathematics: quotient is a mathematical term, and the formula is: (dividend-remainder) ÷ divisor = quotient, and it is recorded as dividend ÷ divisor = quotient ... remainder. Derivation: quotient × divisor+remainder = dividend.

When the number A is divided by the number B (not 0), its quotient is called a complete quotient, for example, 9÷3=3, and 3 is a complete quotient. If the number A is divided by the number B (non-zero), the obtained quotient is an incomplete quotient, such as: 10 ÷ 3 = 3... 1, where 3 is an incomplete quotient.
