一、带余数的除法的概念与性质整数a除以整数b(b≠0),除得的商c正好是整数而没有余数时,我们称a能被b整除。而更多的情况是整数a不能被整数b整除,如9÷4=2……1,像这样被除数除以除数出现了余数的除法称为带余数的除法。整除问题和带余数的除法,可以用下面的形式统一表示:一般 First, the concept and nature of the division with remainder The integer a is divided by the integer b (b ≠ 0), except that the quotient c is exactly an integer and no remainder, we say that a can be divisible by b. In more cases, the integer a can not be divisible by the integer b, such as 9 ÷ 4 = 2 ...... 1, such as the dividend divided by the divisor division appears as division with remainder. The divisibility problem and division with remainder can be unified in the following form: General
