If you were to write down the numbers from 1 to 1000000 in order,

- how many digits would you use?
- how many 0's would you use?
- what would the millionth digit you wrote down be?

For example if you wrote down the numbers from 1 to 20 in order, you'd have

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20.

You would have used 31 digits, 2 zeroes, and the twentieth digit would be
1 (appearing in the 15).
