Preperiod and Period Poser (Posted on 2023-06-09)

If (a,b)ε(0,1), then:

a/b
=               _________________
0.a₁a₂.........a_nb₁b₂...........b_m
    Preperiod      Period

Determine the respective lengths of the preperiod and the postperiod of (10!)^-1

*** Computer program/excel solver methodologies are welcome, but a semi-analytic (hand calculator and p&p) methodology is preferred.
