Auto Fill Series When Value Changes In Another Column?

I am trying to use the auto fill series but I need the series to start over every time the value change in another column.

If i use the auto fill series, it will copy 1,2,3,4,5 and so forth til the end of the column. In this case, i need the auto fill or some other function that will restart once it encounters a different value under the ID column. I've started below to show an example.

IDNo
0.11141
0.11142
0.11143
0.1121
0.1122
0.1123
0.1124
0.1125
