Re: simple Long division problem

hi Xuer

For any division ('long' or 'short'), start by trying to divide into the first digit ie. 7 into 1.  As this 'won't go' then try 7 into 16.  This goes twice ie 2 units so the 2 goes above the 6.

Or think about a simple case such as 14 / 7.  You know this is 2.  16 is a little bigger so the answer should be 2 and a bit.  Doing a rough calculation first often helps.
