See http://www.w3.org/TR/REC-CSS2/visuren.html#floats
"A left-floating box that has another left-floating box to its left may
not have its right outer edge to the right of its containing block's
right edge. (Loosely: a left float may not stick out at the right edge,
unless it is already as far to the left as possible.) An analogous rule
holds for right-floating elements."

If diva and divb must be of fixed width (as against in the equivalent
width ratio) place diva and divb in a containing div of width >= 820px
