long divison


ThIs Is a long dIvIsIon explanatIon about how to do long dIvIsIon, we have been doing long dIvIsIon In our prIme maths group ( 5A )
So basIcally In thIs video we have explained how to dIvIde 168 by 7 but in the long dIvIsIon way, So you start of with 7 and 168, so how much tImes can 7 go Into 1 and of course It can not then you would see how much tImes It can go Into 16 and It can go into 16, ( 2 tImes ) Because the number 7 can go Into 16, the amount of tImes It can go Into the number Is 2 because two sevens make 14.
Then you would place the 2 above the 1 and tImes 2 by 7, that = 14, put the number 14 bellow the 16.
ThIs next step will help you remember the next step easIer, draw a arrow underneath the number 8 and place the number 8 to dIangle from the number 4, next - the 4 from the 6 and that = 2.
With the 28 dIvIde the 7 at the top which = ( 4 ) place the 4 above the 6, the tImes the 4 buy the 7 and that = 28, fInally wrIte 28 bellow the 28, then - 28 by 28 so that = 0 so that means r0.
Pretty much in the end 168 can be dIvIded by 7.
