You're kind of doing each subtraction twice.
You say that 42/25 = 1r17, but then you work out 42-25 as 17 as well, which is a bit unnecessary.
Not showing the second subtraction would also stop it saying that 42-25=175 at the end.
Why did the vector cross the road?
It wanted to be normal.
I think I may redo it, ignoring the remainder. Then show another method where you put the remainder as the difference. That way I will have three alternatives!
