Importance of remainder in division
Division with remainder means that when some objects are divided equally, sometimes there is a surplus. The largest remainder is less than the divisor 1, and the smallest remainder is 1. The calculation method of division with remainder can be divided into four steps, one quotient, two, three subtraction and four ratio.
In remainder division, the remainder must be less than the divisor. In the formula of remainder division, if only divisor is given, the possibility of remainder can be determined, and the range of divisor can also be determined. As long as the divisor, quotient and remainder are determined in the remainder division formula, the dividend can be obtained according to the relationship between dividend and divisor, quotient and remainder.
