All integers are written in a row, starting from one. Determine which digit stands at the 206788th position.

Answer: the digit 7. There are exactly 9 single-digit numbers, 99 - 9 = 90 two-digit numbers, 999 - 99 - 9 = 900 three-digit numbers, 9000 four-digit numbers, and so on. Single-digit numbers will occupy the first 9 positions in the written sequence, two-digit numbers 90 * 2 = 180 positions, three-digit numbers 900 * 3 = 2700 positions, four-digit numbers 9000 * 4 = 36000 positions, and five-digit numbers 90000 * 5 = 450000 positions. Therefore, the digit we are interested in belongs to a five-digit number. The digits belonging to numbers with no more than four digits have numbers from 1 to 9 + 180 + 2700 + 36000 = 38,889. The difference 206788 - 38889 = 167899 needs to be divided by 5 with a remainder: 167899 = 5 * 33579 + 4. The digit we are interested in belongs to the 33,580th five-digit number, i.e., the number 43579 (the first five-digit number is the number 10,000). In this number, the digit we are interested in is in the 4th position.
