How to use long division

To divide by larger amounts we use long division.
  375 / 15  
  Similar to short division but you will not be carrying any amounts

  - Long  division is easier once you have learnt your 12 times tables as it relies on your multiplication skills as you work through the calculation.

Set the calculation out as neatly as possible.
  Start by using multiplication facts to get you as close as quickly possible, try x5, x10 orx20 to start with, making sure you are less than or equal to the amount you are dividing into.

  We have used 15x20=300 as our first calculation, so we subtract 300 from 375 which leaves 75

Now we are left with the calculation 75/15 so we repeat the process.
  Start by using multiplication facts to get you as close as quickly possible, try x2, x3 or x5 to start with, making sure you are less than or equal to the amount you are dividing into.

  We have used 15x5=75 as our first calculation, so we subtract 75 from 75 which leaves 0, so we now need to add up all the amounts that we have multiplied 15 by, we have 15x20 and 15x5, so you now add 20+5=25, so 375/15=25

 

  - Long  division is simply the use of the inverse operation (multiplication). you just keep on subtracting the amounts you have found until you get to 0 or you may end up with a remainder which you could leave as a remainder or carry on dividing the other side of the decimal point.
