-- Problem 26
-- A unit fraction contains 1 in the numerator. The decimal representation of the unit
-- fractions with denominators 2 to 10 are given:
--
-- 1/2   =   0.5
-- 1/3   =   0.(3)
-- 1/4   =   0.25
-- 1/5   =   0.2
-- 1/6   =   0.1(6)
-- 1/7   =   0.(142857)
-- 1/8   =   0.125
-- 1/9   =   0.(1)
-- 1/10  =   0.1
-- Where 0.1(6) means 0.166666..., and has a 1-digit recurring cycle. It can be seen
-- that 1/7 has a 6-digit recurring cycle.
--
-- Find the value of d < 1000 for which 1/d contains the longest recurring cycle in
-- its decimal fraction part.
