Hint: the 10th character is the letter O (not the number zero)

My thought

| Comment 4 of 6 |

I noticed the A's at the beginning and the end with 16 figures between them. The decimal expansion of 100/17 repeats every 17th digits. 5.8823529411764705882352941176470588...

So to me it suggested 17.

(But I like the official solution better)
