    Division

    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}

    You know I never thought of doing it like a fraction. I did it the long way with multiplication and subtraction.
