How do you divide 900 by 30?

Answer 1

It would be easier if you got rid of some of the zeros. You can safely remove a zero from both 900 and the 30, leaving you with 90 and 3. Then you can temporarily ignore the remaining zero and divide the 9 by 3, leaving you with 3, and since we ignored the zero, we have to add it back to the result. Thus our answer is 30.

By the way, 30 is the square root of 900, so 30 x 30 gives you 900.

Or you can divide it the conventional way, though you don't have to. In that case you figure out how many time 30 goes into 90, and that is 3 times evenly. Then you have the zero left and 30 does not go into zero, so you have the answer of 30 at the top of your work, and no remainders.
