Comment (by dsm):
Could you add some doctests to confirm that the floor division works as
you would expect it would by analogy with the integers, i.e. `(x//y)*y +
(x % y) == x?` [Possible typo there, haven't finished this coffee.] It
seems to:
{{{
sage: R.<x> = QQbar[]
sage: left = x*3+4
sage: y = x
sage: (left//y)*y + (left % y) == left
True
sage: y = 17
sage: (left//y)*y + (left % y) == left
True
sage: y = (2*x+7)
sage: (left//y)*y + (left % y) == left
True
}}}
If floor division wasn't working then there must not have been anything
testing stuff like this.
