Answer:
you start by seeing how many times 8 goes into (7) which is zero Then you add the (8). 
how many times does 8 go into 78 = 9 with 6 left over. 
you bring the 6 down and the next 8 giving you (68) = 8 with 4 left over 
so you bring the 4 and the two down giving you (42) = 5 with 2 left over. 
so your answer is 985 remainder 2
