4000 devided by 19 is equal to 210 how can it possible ?

Question

4000÷19=219

Answer 1

It isn't possible.  The answer is 210.526.... and if you round it off, you can get 210 depending on the rules you use for rounding.  If you use significant figures, you actually get an answer of 200 (1 sig. fig. based on the value of 4000).
