小数除以小数的竖式如何书写
除数是小数时:先把除数变成整数,除数扩大到原来的多少倍,被除数也要扩大到原来的多少倍(即小数点也向右移动几位,位数不够的用0补),然后按照除数是整数的除法进行计算。计算小数除法,除到被除数的末尾仍有余数时,在余数后面添0继续除;计算过程中,哪一位上不够商1,就在那一位上商0占位。<br><img><br><h2>小数除法竖式计算过程</h2><br>除数是整数的小数的除法<br>除数是整数的小数除法,可按照以下步骤进行计算:<br>①先按照整数除法的法则去除;<br>②商的小数点要和被除数的小数点对齐;<br>③除到被除数的末尾仍有余数时,就在余数后面添0,再继续除。<br>除数是小数的小数除法<br>除数是小数的小数除法,可按照以下步骤进行计算:<br>①先把除数的小数点去掉使它变成整数;<br>②看除数原来有几位小数,就把被除数小数点向右移动相同的几位(位数不够时补0);<br>③按照除数是整数的除法进行计算。
