Is there a way to find out where a number lies in a range in ruby?
Let's say I have a `min` and a `max` number. `max` can be anything, but `min` will always be greater than zero.

I can get the range `min..max` and let's say I have a third number, `count` -- I want to divide the range by 10 (or some other number) to get a new scale. So, if the range is `1000`, it would increment in values of 100, 200, 300, and find out where the count lies within the range, based on my new scale. So, if `count` is 235, it would return `2` because that's where it lies on the range scale.

Am I making any sense? I'm trying to create a heat map based on a range of values, basically ... so I need to create the scale based on the range and find out where the value I'm testing lies on that new scale.

I was working with something like this, but it didn't do it:

    def heat_map(project, word_count, division)
        unless word_count == 0
          max = project.words.maximum('quantity')
          min = project.words.minimum('quantity')
          range = min..max
          total = range.count
          break_point = total / division
          heat_index =  total.to_f / word_count.to_f
          heat_index.round
        else
          "freezing"
        end
      end

I figured there's probably an easier ruby way I'm missing.
