How do I do long division the easy way?
The steps are more or less the same, except for one new addition:
- Divide the tens column dividend by the divisor.
- Multiply the divisor by the quotient in the tens place column.
- Subtract the product from the divisor.
- Bring down the dividend in the ones column and repeat.
How do you estimate division?
Check Division with Multiplication
- Do the division problem.
- Multiply the quotient times the divisor.
- If there is a remainder, add it to the multiplication product.
- Compare this answer to the dividend. They should be the same number (630 = 630).
What grade do you teach two digit division?
This is a complete lesson with examples and exercises about two-digit divisor in long division, meant for initial teaching in 5th grade. The first exercises have grids to complete the division, and space for students to write the multiplication table of the divisor in the margin.
Do you write the multiplication table of the divisor before you divide?
Often, it is helpful to write the multiplication table of the divisor before you divide. Example 1. The division is by 16. Here is the multiplication table of 16: 16 goes into 5 zero times, so we look at 55.
What is the remainder of 32 divided by 224?

How do you do division exercises?
The first exercises have grids to complete the division, and space for students to write the multiplication table of the divisor in the margin. Then there are conversion problems between inches/feet and ounces/pounds, because those are solved with division. Often, it is helpful to write the multiplication table of the divisor before you divide.
