If you started by thinking about long division of 352/4, then would you realize that 8 is the first digit of the quotient?
Just a thought ...
I'm doing some random online tests and realised my arithmetic skills are next to useless. One question was 352.51 ÷ 4.18 = ? Now I did what I always do - remove the decimal points and just do 35251/418, then placing the d.p. in the correct location but in this case if I'm using long division I come to a place where I'm dividing 3525 by 418 which, with a bit of trial and error comes out to be 8 (+the remainder) but it seems like such a waste of time checking whether 8 is the first number to go on top. Any help on what I should be doing to quicken the process would be appreciated
