I am trying to complete an autofill in excel

The numbers are 900000824-1, 90000825-1, 900000826-1 to 900001133-1

I have tried typing 900000824-1 into cell A1, 90000825-1 into cell A2,
900000826-1into cell A3, when I try to fill I get 900000824-2, 90000825-2,
900000826-2 in A4, A5, A6 (respectively).

Have tried to creat a custom fill series with no luck either, any assistance
will be most appreciated.

Thank you.
