N is a duodecimal (base 12) positive integer having precisely 50 digits such that each of its digits is equal to 1 except the 26th digit. If N is divisible by the duodecimal number 17, then find the digit in the 26th place.

(In reply to Now it's correct by Larry)

"...Any number which is 10mod19 which is divided by 11 becomes 13mod19.

Hardly the right wording.

13 is the z zolution of 19m+10=11z
(  all  integers between 0 and 18 inclusive)    

since 19*7+10=11*13
