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!
The 42nd digit of pi is 6. (The first 43 digits of pi are 3.141592653589793238462643383279502884197169. If pi were rounded to the nearest 42 digits, then the 6 would be rounded up to a seven.)
Not including the initial digit, the first 23 decimal digits of pi are 3.14159265358979323846264.
