分析：除數(shù)是小數(shù)的小數(shù)除法的計算法則為：先看除數(shù)中有幾位小數(shù)，就把被除數(shù)的小數(shù)點向右移動幾位，數(shù)位不夠的用零補足； 然后按照除數(shù)是整數(shù)的小數(shù)除法來除．由此可知，在計算除數(shù)是小數(shù)的小數(shù)除法中，要將除數(shù)化成整數(shù)來除．
解答：解：根據(jù)除數(shù)是小數(shù)的小數(shù)除法的計算法則可知，
在計算除數(shù)是小數(shù)的小數(shù)除法中，要將除數(shù)化成整數(shù)來除．
故答案為：除數(shù)．
點評：本題重點考查了除數(shù)是小數(shù)的小數(shù)除法的計算法則．
