    Fixed the FindBug issue by avoiding an incorrect integer division. I based 
this on an old unmerged pull request for this bug: 
https://github.com/apache/beam/pull/853
    
    That PR also included a new unit test for ApproximateQuantiles.java, wasn't 
sure if I should also include that unit test.
