北師大版五年級上冊數(shù)學(xué)知識點(diǎn)匯總第一單元 小數(shù)除法1、除數(shù)是整數(shù)的小數(shù)除法計(jì)算法則：除數(shù)是整數(shù)的小數(shù)除法，按照整數(shù)除法的法則去除，商的小數(shù)點(diǎn)要和被除數(shù)的小數(shù)點(diǎn)對齊;如果除到被除數(shù)的末尾仍有余數(shù)，就在余數(shù)后面添0再繼續(xù)除。2、除數(shù)是小數(shù)的小數(shù)除法計(jì)算法則：除數(shù)是小數(shù)的除法，先移動除數(shù)的小數(shù)點(diǎn)，使它變成整數(shù);除數(shù)的小數(shù)點(diǎn)向右移動幾位，被除數(shù)的小數(shù)點(diǎn)也向右移動幾位
