You mean (2+3+4)/3

Why post the same question twice in a row? Post your question once.

my question was that for this method shall we consider zero,s

In your example, you did not include zeros so Azzi didn't either. However we don't know why the last non-zero column in "2+3+4/2" - the 4 only - was divided by 2. Why 2, and why divide only the 4 by some number and none of the other numbers????
