There is no last digit. It's a repeating decimal representation of a rational number. 1/3 is such a number, represented by 0.33333...
This is the sum of an infinite series, 3/10 + 3/100 + 3/1000 ... Your answer doesn't have an 8 because that's not the value of the number you cited. Your series is:
123456790/10^9 + 123456790/10^18 + 123456790/10^27 ...
Your assignment now is to find the rational number represented by the series you want to have:
1234567890/10^10 + 1234567890/10^20 + 1234567890/10^30 ...
Do your experimenting with smaller series before you tackle the big one.

the last digit will always be nine and theres no 8 becuz if you multiply that number by 81 you get 10

seems like the 12345679 just keep repeating themselves. 9 is the last digit, the 0 is the 1st in the repeating sequence. One of those neverending math answers, theres no 8 because that would just make too much sense.

there is no last digit b/c it goes on forever, and there's no 8 b/c 123456790 is repeated infinitely.
Proper question to ask is why is there the rest of the digits, and in right order too.
