The dividend is represented by the space separating the two verses.
Build a bridge by defining:
- the divider: a length of board
- the quotient: the number of boards
- the rest: an additional and optional board

Different game modes:
- free play: to freely build different bridges
- division without remainder: dividends and divisors are taxed, you have to find the quotient (without remainder)
- division with remainder: dividends and divisors are imposed, you have to find the quotient and the remainder.

The "Information" button at the top left of the main menu explains how the application works.
