The calculation method of remainder division can be divided into four steps: one quotient, two multiplication, three subtraction and four ratio.

(1) Quotient: Trial Quotient. If you want to multiply the divisor by a few, the nearest dividend is less than the dividend, then the quotient is a few, written on the unit of dividend.

(2) Multiplication: multiply the divisor and quotient, and write the number below the dividend.

(3) Subtraction: Subtract the product of quotient and divisor from the dividend, and write the difference below the horizontal line.

(4) Ratio: Compared with the divisor, the remainder must be small.
