There are a lot of people who would like to teach people how to do long mathematics, but they do not know how they should begin.
These are the steps that you need to take:
• Divide the tens column with the divisor.
• You would need to multiply the divisor by the quotient that you will get when you go to the tens place.
• You would need to subtract the product that you will get from the divisor.
• Then you need to bring down the dividend that you will get to the one's column.
You need to do the process until you get the final answer. To make it easier to teach math, it will be helpful if you would use a pen and paper to describe the process. The person learning it should also know the various number of positions.
