I think this looks pretty good. You lose some granularity on the number, but no extra CSS is required to shrink the numbers or realign stuff. Unfortunately, the leading '0' won't fit.
Here's some more precision with a smaller 'm'.
<div class="views"> <div class="mini-counts supernova">.12<span style="font-size: 50%;">m</span> </div> <div>views</div> </div>
