Let x=0.135792468135792468135792468... then 1000000000x=135792468.135792468135792468135792468...

Clearly, 1000000000x-x=135792468 (i.e)999999999x=135792468

Therefore, x= $\frac{135792468}{999999999}$

Hence need to find the remainder of(135792468+999999999) divided by 17.

The required result is 10.
