Rational numbers

The pictures below show the base 2 digit sequences of numbers m/n for successive m.

The digits of 1/n in base b repeat with period

MultiplicativeOrder[b, FixedPoint[#/GCD[#, b] &, n]]

which is equal to MultiplicativeOrder[b, n] for prime n, and is at most n - 1. Each repeating block of digits typically seems quite random, and has properties such as all possible subblocks of digits up to a certain length appearing (see page 1084).
