(42, all flavours) Integer Division - how?

[robve]

Using the int function (or floor function), the quotient Q and remainder R of Y/X is simply:

Q = sign(X)*int(Y/abs(X))
R = Y-Q*X

This satisfies Y=Q*X+R, 0<=R<|X|, for any Y and X!=0.

I've always used this formulation, rather than fiddling with MOD.

Is there a downside to this method, I mean in general, not specific to the 42?
