The division you're attemping is integral.

The result of ( avail / total ) is obviously less than 1, and it will
result in an integral result (0) rather than a float. Already you've
truncated your result.

Try:

    float( avail ) / float( total ) * 100

or:

    ( avail * 100 ) / total

Note that in the second case, you won't yield any decimal places in the
resulting percentage. If you want those to reflect reality, use the first
method to use floating point division rather than integral division.
