"Division beads" are a concept I came up with to visualize divison. A string of beads is laid out in a rectangular area. The quotient and remainder can be found through simple counting. For example:
$ python3 -m divisionbeads
Enter a division problem (example: 23 / 7) or QUIT.
> 23 / 7
23 / 7 = 3 r 2

Enter a division problem (example: 23 / 7) or QUIT.

40 / 10 = 4 r 0
