This one is popular and new. I was taught it by a trainee teacher last year.

Long division is 9829 / 71 - or when both numbers in the sum are more than one digit long and usually more (or greater than the highest multiplication table you already know). Same technique though, just takes a bit longerBlog? What blog...?Comment
