Any rational number x can be represented by a finite simple continued fraction.

              1    1          1
    x = a0 + --   --         --
             a1 + a2 + ... + an
For example,
      355          16          1            1           1    1
     ----- = 3 + ----- = 3 + ----- = 3 + ------- = 3 + --   --
      113         113         113             1         7 + 16
                              ---        7 + --
                               16            16
