Hi Gordon,

We could express the result of your division like this:

y/x = a + b/100

where a is the integer part of result and b/100 is the fractional part. If
you use an integer division, then you immediately get a and remainder r:

y/x = a + r/x

Now, we need to get b. We know by substituting y/x in the first
equation that

r/x = b/100

From that we express b:

b = 100*r/x

So, the algorithm would be:

1) divide y by x to get a
2) multiply remainder r by 100
3) divide 100*r by x to get b

It should work with the routine you found, if the ranges of numbers
are right.
