小数点的除法该怎样做？要举几个例子！

1.2/3=0.4,怎么说呢,我算的时候是把小数点的去掉,就是把他们用整数算,等算好了,再把小数点加上去,就是向左移动小数点,我的表达能力就是这样了,不知道你懂不

1.常规做法：跟整数除法一样做，如：
``````````````````````````2 . 0 3 2 ……
````````````````````````________________________________
````````0`.`0```2```8/``0 . 0 5 6 9
`````````````````````\/```0 . 0 5 6
`````````````````````````_______________________
``````````````````````````0 . 0 0 0 9 0
``````````````````````````0 . 0 0 0 8 4
`````````````````````````___________________________
``````````````````````````0 . 0 0 0 0 6 0
``````````````````````````0 . 0 0 0 0 5 6
`````````````````````````_______________________________
``````````````````````````0 . 0 0 0 0 0 4 0
``````````````````````````……

（由此题可知，小数除法在除不尽时无余数，
只需按照题目要求取若干位小数即可。）

2.特殊做法：将除数和被除数同时扩大若干倍至整数，再按整数除法做，如：
0.8除以0.02等于80除以2等于40。
