Four does not go into 81 evenly. But as "evenly" was not a defined requirement for the answer. 4 goes into 81 20.25 times
81/19 = 4.263 (approx).
4 can go into 81 twenty whole times. After that, the 81 is still not full, but there is onlyenough room left in it for ' 1 ' more, so it is not possible to jam the entire 4 in again.If you're allowed to cut the 4 up in pieces, then you can use ' 1 ' to fill up the restof the 81, and then unobtrusively discard the 3 that you have left over.
