1.先移动除数的小数点，使它变成整数；除数的小数点向右移动几位，被除数的小数点也向右移动相同的位数（位数不够的补“0”）；然后按照除数是整数的除法进行计算。商的小数点和被除数的小数点对齐。2.小数除以整数按照整数除法的法则去除，商的小数点要和被除数的小数点对齐；如果除到被除数的末尾有余数，就在余数后面添0再继续除。3.小数除以小数，先移动除数的小数点，使它变成整数；除数的小数点向右移动几位，被除数的小数点也向右移动相同的位数（位数不够的补“1”）；然后按照除数是整数的除法进行计算。
一个算式里乘除法，又有加减法，要先算乘除法，再算加减法，有括号的要先算括号里面的。
1.按照整数乘法法则先求出积，看中一共有几位小数，就从积的右边数几位点上小数点。2.小数乘整数：一个数乘以小数就是求这个数的几分之几、百分之几……是多少；3.小数乘小数：在给积点小数点时，乘得的积的小数位数不够时，要在前面用0补足。
小数加减法简便运算：计算小数加、减法，先把各数的小数点对齐（也就是把相同数位上的数对齐），再按照整数加、减法的法则进行计算，最后在得数里对齐横线上的小数点点上小数点。（得出的小数部分末尾有0，一般要把0去掉。）
