Class summary

When doing column-vertical division, be sure to follow the order of writing: first write the division sign, then the dividend and divisor, then find the quotient, the product of the quotient and the divisor is written below the dividend, and finally write the remainder.

How to test the quotient of division with remainder: Use the multiplication formula to find out which number the divisor is multiplied by which the product is closest to the dividend and smaller than the dividend. Then this number is the quotient.
