Given a fraction of two relatively prime integers of lengths m and n, what is the maximum number of decimal places (in the decimal expansion) before the expansion starts repeating? For example I happened to compute the ratio of two four digit numbers and the answer to 15 places had no repeats. I do not know when the repeats would start.
This question differs from a "duplicate" question. I am asking for how many digits (maximum) BEFORE it starts repeating. Referred question is length of repetition.
