A US Billion has 9 digits following the leading number(s): 202,700,000,000 The European system uses a different billion than the US (although many countries have adopted the US Billion -- as it works better with currencies). That variation is a million million (12 digits following the leading number(s)): 202,700,000,000,000

There are 70,674 3's in the first million digits of pi. * * * * * There are 100,230 3s and 100,106 9s. Since the decimal representation of pi is essentially random, the number of times any digit appears should be approximately 10% of the total number of digits. So, for a million digits, there should be around 100,000 of any digit so it should have been immediately apparent that the previous answer was extremely unlikely. In fact it was incorrect to a very large degree!
Infinity is not a number, and has no digits.The only things numbers and digits can represent are finite amounts, and infinity is, by definition, not finite. It therefore has no digits, cannot be equated like a number, and has no 0's, 1's, 2's, 3's, 4's, 5's, 6's, 7's, 8's or 9's.
