# 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.
