The rational number 23949 divided by 99990 has the decimal representation expressed in what appears a nonperiodic, plus a regular part: 0, 0023940239402394023940 ... This decimal representation, the first digit 2 occupies the third decimal place and the first digit 9 occupies the fifth decimal place. Watching these patterns of repetition, we conclude that the figure occupies the decimal 10 raised to the number 10 − 1 = 10000000000 − 1 is the digit? :furioso:

Hint: You know the pattern 23940 is repeated every five spaces after the first two 0's. So what is the largest integer n such that 2 + 5n < 10^(10)  1? Dan
