"Long" Division
Note Yes, it is the popular opinion that there is no real need to put so much effort into solving longdivision problems when you have calculators that can do all the monotonous work for you. The trend in education and the workplace is away from the need for button pushers and toward people who understand fundamental principles and know how to use them to solve problems as we've never faced before  even if the work is sometimes dreary.. 
Examples of Long Division
Carefully study the details of these examples of long division. Do not quit until you are sure you understand every step in every example you see.
Exercises for Long Division
Use long division to solve these examples. Keep working them until you have completely mastered the process.
