when we multiply 89.635 by 8, we get 0 at unit's digit. Now multiplying 89.635 by 10 will give 5 at tens' digit. Now we know , after multiplication of decimal numbers, the number digits to the right of decimal is equal to the sum of digits to the right of both muliplicand and multiplier. so the answer becomes 7.

rewriting the give numbers as (89635*2218)/1000*100000 i.e.,we have 8 zeros in the denominator so we get 8 digits after decimal point but last number is zero because of 5*8=40 so answer is 7
