Re: Mandy Jane's Corner

By the way your previous answer " 2 x 13 = 26 with 9 left over" is correct.

Re: Mandy Jane's Corner

Yes. That is correct. Right. I am going to give you an image of where we are now up to.
I have left out the arrows to save time.

Can you see the next step ?

Re: Mandy Jane's Corner

next step is to bring down the 4 so you have 94 is that right?

Re: Mandy Jane's Corner

Yes that is correct. Now how many times does 13 go into 94 ?

This is tricky because we don't know the 13 times table.

So you could start from 0 and add 13 successively. (0, 13, 26, 39, .... )

Or. Guess the number and multiply by 13 to check whether it is the right one.

Re: Mandy Jane's Corner

You have got the right idea with that, but it is a bit muddled.

13 x 7 = 91   then 94 - 91 = 3

I am going to update you with a new snapshot.....

Re: Mandy Jane's Corner

Yes that is correct.

No we have to work out how many times 13 goes into 39. Something interesting happens here.

Re: Mandy Jane's Corner

By the way I have prepared another image of the final state of the division.

Before I post it though. Can you see what the answer to the original question is ?

Re: Mandy Jane's Corner

In answer to the previous post. Yes 3 does go up the top in the answer bit.

The remainder is zero. Notice that if this happens and there are no more numbers to put down then the
calculation is finished and you can interpret the result.

Re: Mandy Jane's Corner

ok so the answer is 0 then is that right?

Re: Mandy Jane's Corner

Well the answer to the subtraction at the end is zero and this tells us that the remainder is zero.
This combined with the fact that we have used up all of the digits tells us that the calculation should be finished.

What is the answer to the original question?  What is  16549 divided by 13 ?

Re: Mandy Jane's Corner

Yes, but we usually would not include the 0 at the start of that number so really the answer is 1273.

I will make up a few examples in a minute and post them.

Re: Mandy Jane's Corner

Okay some examples for you to have a go at:

7479 divided by 9 ?

3227 divided by 7 ?

7860 divided by 15 ?

5508 divided by 17 ?

They should all result in a nice round number as an answer. (If not then one of us has made a mistake.)

In practice not very many divisions work out with a whole number as an answer we may have to
discuss concepts to do with remainders, fractions and decimals at the end of the answer.
However let's leave that for now and concentrate on the long division technique.
