如果是，那么商的位數(shù)就是被除數(shù)的位數(shù)減位數(shù)加1；如果被除數(shù)的前三個(gè)位數(shù)小于除數(shù)，那么商的位數(shù)就是被除數(shù)位數(shù)減去除數(shù)位數(shù),3位數(shù)除以二位數(shù)先除以被除數(shù)的高位，除數(shù)為2位數(shù)，取決于被除數(shù)的前兩位,大于二位數(shù)除法的被除數(shù)稱為二位數(shù)除法,2.除數(shù)從高位開始是二位數(shù)除法正則整數(shù)除法,除數(shù)從高位開始為一位數(shù)除法規(guī)則整數(shù)除法,多位數(shù)除法常規(guī)整數(shù)除法從高位。{0}1、三位數(shù)除兩位數(shù)豎式計(jì)算3位數(shù)除以二位數(shù)先除以被除數(shù)的高位，除數(shù)為2位數(shù)，取決于被除數(shù)的前兩位。多位數(shù)除法常規(guī)整數(shù)除法從高位。除以幾，看有多少。這個(gè)還不夠看下...
