Why would it have to use division, or for that matter, any kind of math at all? I imagine that as each new visitor is recorded, they simply count how many other visitors had the exact same browser configuration.
The "one in x browsers have this value" column is probably just for informative purposes (and not the raw data that was somehow munged to determine the uniqueness of your browser fingerprint).
I'm not sure what you mean by "resolution"; the site doesn't claim that a browser fingerprint is unique among all instances of all browser software ever run, just that (for example, to quote from my test results) "Your browser fingerprint appears to be unique among the 2,568,783 tested so far".
