"Helping" Emily with her maths homework

Emily is learning how to do Euclidean long division and unfortunately I do not seem to be able to help her with it. Seeing as I am absolutely sure that I remember how to do long division, it must be the Euclidean bit that is confusing me. I do think it is most unfair to expect young children to cope with advanced mathematics when not even someone with a maths O-level can understand what is going on.

(And I've a good mind to write a strongly-worded letter to this chap Euclid to tell him just what I think of him...)
