I guess the question is : 919 + 6  divided by 8

So, 919 can be written as  (8 + 1)19 and on its binomial expansion all the terms will have  a multiple of 8 except the last term 119 so all the multiple of 8 will be divisible by 8 except the last 1 which will be remainder.  So overall remainder will be 1 + 6 = 7
