Operation formula: dividend-divisor = quotient; Dividend quotient = divisor; Quotient divisor = dividend; There is a remainder: dividend γ divisor = quotient ... remainder (where the remainder is less than divisor), divisor× quotient+remainder = dividend.

Operational nature of the Division:

The dividend is enlarged (reduced) by n times, and the quotient is correspondingly enlarged (reduced) by n times under the condition that the divisor is unchanged. The divisor is expanded (reduced) by n times, while the dividend is unchanged, and the quotient is correspondingly reduced (expanded) by n times.

Dividing by two divisors in succession is equal to dividing by the product of these two divisors. Sometimes simple operations can be performed according to the nature of the division. For example: 300 ÷ 25 ÷ 4 = 300 ÷ (25× 4) = 300 ÷100 = 3.
