I originally believed this was correct,
and it is symmetrical with multiplication. But now
I am not sure. Consider
3.3 / .02
That is like:
330 / 2 = 165
By your formula, then, the quotient would be
since the number of places is 1 - 2 = -1.
The remainder is then
3.3 - (160 * .02) = .1
This seems strange, since the remainder is now
bigger than the divisor. I suspect that this
might be confusing. I'm confused!
If your formula is NOT accepted, on the other hand,
there's no way to 'undo' a multiplication.
.1 * .1 = .01
Since I insisted the quotient is always an integer,
the result of any division of .01 by .10 would have
to be 0 with remainder .01.
So my rules are inconsistent. :-(
I think your rule MUST be accepted.
