Hi Anupama,

This is not a good method for division by 13, but you can still do it – either using bar numbers, or by reducing digits.

With bar numbers:
13  )  <span style=”text-decoration: underline;”>2  5  4  6</span>
<span style=”text-decoration: underline;”>2  (1)  7 rem -15</span>  = 197 rem -15  =  195 rem 11

Just follow through with the method given and you get:  2  (1)  7 rem -15.

Then remembering the the 197 is 197 thirteens you will need to take two of them over to deal with the negative remainder: 26 – 15 = 11.

The other way starts by noting that you can’t take 3 twos from 5, so you put down 1 and put the other 1 to the left of the 5 to make it into 15. And proceed like that.
