Is there any trick to dividing a four digit number by a three digit number? For example

125/1200

We cant use calculators because they want us to learn how to do it on paper. I know how to do it if it was dividing any number by a one digit like.

Hi Saphtalon,

From your second example, I guess you are looking for $\displaystyle\frac{1200}{125}$

Since 125 multiplied by 4 is 500, multiply the fraction by $\displaystyle\frac{4}{4}=1$

$\displaystyle\frac{4}{4}\ \frac{1200}{125}=\frac{4800}{500}=\frac{48}{5}$
