This tutorial demonstrates how to easily scaffold for a better understanding of long-division, by using multiples.
If your students can perform the following three skills, they already have all they need to master long division.
1) Recognise multiples of a number
2) Multiply and divide by powers of ten (10, 100, 1000 etc)
3) Break numbers into parts through addition or subtraction
BONUS: This method also promotes a better understanding of place value
