About this fraction
Sevenths are notable because they all produce the same recurring digit sequence in different rotations: 142857. 5/7 = 0.(714285). Watch for the cyclic pattern in the decimal expansion. The denominator has prime factors other than 2 and 5, which is why the decimal repeats forever.
