The 40,000th digit will be 1.
Numbers 1 - 9 use 9 digits (cumulative 9)
Numbers 10 to 99 use 90 x 2 digits = 180 (cumulative 189)
100 to 999 use 900 x 3 digits = 2700 (cumulative 2889)
1000 to 9999 use 9000 x 4 digits - 36000 (cumulative 38889)
10000 to 10221 uses 222 x 5 digits = 1110 (cumulative 39999)
The next number is 10,222 and the first digit of this number is the 40,000th digit written, which is 1.

The 40,000 digit will be "1" in the number 10,222. I used Excel and the "len" function to find the answer.

I think it is 0 as the 1,2,3 ..0 keeps repeating itself every ten terms.
