How do you apply a function to all values in selected cells?

I was entering timesheet data (in minutes) into an Excel spreadsheet. Then the requirements changed - the data actually needs to be in hours. Is there a way to divide all the cells by 60 in place without using formulas? Ideally, I'd like to select all the cells and somehow say "Divide by 60."

Note: I've answered my own question in the hopes that others might find it useful (or provide a better solution!).

It turns out you can do exactly what I wanted:

1. Enter the number 60 into another cell, doesn't matter where.
2. Copy that cell (ctrl-C).
3. Select the cells you want to modify.
4. Right-click, paste special.
5. You get some options of what operation you want to apply. I picked Divide for my case.
6. Magic! All the selected cells' values are now divided by 60. You can even delete the cell you used for the number 60.
