Do float division with `fdiv`

Usually in ruby, when I need to perform floating point division I call .to_f on either the numerator or denominator, like this:

1 / 5.to_f
# 0.2

While many people might read this as floating point division instead of integer division, reading it that way gets trickier when those numbers are variables and the .to_f happens somewhere else.

You can be more explicit about the operation you are performing with .fdiv.

# 0.2

This works with floats as well, so that you can use fdiv in any context.

# 0.2
