Each letter in the long division below (which shows that CDE divided by AB is F with a remainder of JE) represents a different digit from 0 through 9. No number begins with 0. Can you decipher the long division? (Note: it's in base 10.)
| Code: |
___F
AB)CDE
GHI

| I believe that 416 / 78 works. It's quite a nice puzzle, because at first glance it looks like it will take a lot of trial and error, but, in fact, it takes very little. |
