The expression is:

To divide this quantities, first we need to convert 8 and 1/8 to a fraction.
We do this as follows:

As you can see, to make the conversion we multiply the whole number by the denomitar and add the numerator (8x8+1) and divide by the same denominator.
So the division to make is:

A division between two fractions is made as follows:
So applying this to our division we get:

The answer is: 39/4, which represented as a mixed fraction is:
