#63#

Explanation:

Let's think of #504# as #500+4#.

Now, remember that #(a+b)/c=a/c+b/c#

Therefore, #504/8=(500+4)/8=>500/8+4/8#
Let's keep going on like this.

#500/8+4/8=>400/8+100/8+4/8#

Try to focus on the fractions that do not divide evenly out as an integer.
#=>20/8+400/8+80/8+4/8#

#=>16/8+4/8+400/8+80/8+4/8# We simplify the fractions.

#=>2+1/2+50+10+1/2# We add them up.

#=>63#

This solution, of course, is not the "standard" way, but I thought of it as an interesting way to show how wonderful algebra is.
