Yes that is fine. Right I have trimmed my image file down so as to just show you the first step

that I did in my answer. Can you work out what the next thing to do is? Remember that we are

dividing 16549 by 13 here. All I have really done is set out the answer, observed that trivially

1 divided by 13 gives us 0 remainder 1 and dropped down the 6 with an arrow.

So we have the appearance of the number 16 as the next bit of the problem that we are trying

to divide by 13. What happens next?

To get the numbers to appear centrally click and highlight the cells that you wish to make central.

Then click the right mouse button and choose "Format Cells", choose "Alignment" and then

choose "Center" for the "Horizontal " and "Vertical" text alignment.

Then go to the "Font" option at the top. Select a reasonable size like "16". Click OK.

To get a line at the bottom of a row of numbers:

Select the cells that the numbers are in or will be in.

Click the right mouse button and choose "Format Cells", and choose "Border", then

select the bottom left of the "line style" options. Then select which "Border" you want

and click OK.

I have created the lines of the division entirely using the "Border" option.

I will stop at that point so that this post does not go on for too long, but you could have

an experiment with Excel to see what you can do.

(The next stages are to get a "PRTSC" (Print Screen) and to paste it in Paint and then

to "Crop" the item, do any editing in Paint that it needs and save the file as a GIF file

remembering to make it reasonably small so as not to use excessive memory).

hi mathgogocart

These instructions are for a PC running Windows with MS Excel and Paint. I'm fairly sure Mandy has what is needed. If you give me more details about why it didn't work for you, I'll try to think up a 'work-around'.

I am going to give you the next step of the 16549 divided by 13 question.

Notice that the first "0" in the answer at the top (top left) comes from the fact that 0 x 13 = 0.

We get the first remainder by 1 - 0

The remainder of this first bit was 1. This is "worth" ten when it is shifted to the right.

This is added to the 6 which we dropped down and they add to give 16.

Then I note that 1 x 13 = 13. The 1 from this is the next digit of the answer.

Now what do we do ?

You are right to subtract them. That is to say the "16 - 13" bit was right.

However 6 is not right. Try again.
