In a division formula, the relationship among dividend, remainder, divisor and quotient is: (dividend-remainder) ÷ divisor = quotient, which is recorded as dividend ÷ divisor = quotient ÷ remainder, and then the quotient × divisor+remainder = dividend is derived.
Complete quotient and incomplete quotient
When the number A is divided by the number B (not 0), it is called a complete quotient. For example, 9÷3=3, and 3 is the complete quotient.
Incomplete quotient means that if the number A is divided by the number B (non-zero), the obtained quotient is incomplete. For example: 10 ÷ 3 = 3... 1, where 3 is an incomplete quotient.
