Let's assume that the cells are in a column (say A):
1. insert a helper column near by
2. format the cells in the helper column as text
3. in the helper column insert
="0"&A1
4. copy this down
5. copy the helper column and paste it as value back into Column A.

You can avoid this if all your numbers are of fixed length, then use custom
formatting:

Format Cells Number Custom

and enter as many zeros as you like
