No, it's not possible. See the explanation below. Division is really repeated subtraction, e.g. you can find out how many sevens there are in 49 by seeing how many times you can subtract 7 from 49. Of course the answer is 7 Similarly when you are thinking of dividing 12 by zero you are really asking how many times can I subtract zero from 12 (until there is nothing left). Of course it cannot be completed, even if you were subtracting for ever. Something divided by zero remains as the original something.
