What is the standard procedure for dividing?

All you do is divide the first number of your given dividend by the first digit of the divisor. Then write the result of that division in the space of sed quotient. Now you want to multiply the digit of the quotient by the divisor, finally write the result beneath the dividend and subtract it.

How do you estimate using compatible numbers?

Compatible numbers are pairs of numbers that are easy to add, subtract, multiply, or divide mentally. When using estimation to approximate a calculation, replace actual numbers with compatible numbers. The numbers 500 and 300 are compatible for addition, since the sum of 800 can be easily calculated mentally.

How do you estimate quotients?

To estimate the quotient, we first round off the divisor and the dividend to the nearest tens, hundreds, or thousands and then divide the rounded numbers. In a division sum, when the divisor is made up of 2 digits or more than 2 digits, it helps if we first estimate the quotient and then try to find the actual number.

How do you divide multi digit numbers?

Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it.

What do you do with the divisor when you estimate the quotient?

When to teach two digit divisor in math?

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 divisor before you divide?

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. Example 1. The division is by 16. Here is the multiplication table of 16:

How do you do long division with two digits?

Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it. If you cannot, because the dividend is smaller, you will have to choose a smaller number in the quotient until it can subtract.

Which is an example of a two digit divisor?

Example 2. We are dividing by 32. Here is the multiplication table of 32: 32 goes into 47 once. 32 goes into 150 four times. 32 goes into 224 seven times. Notice there is a remainder. 1. Divide. First write a multiplication table for the divisor. Check each answer by multiplying. 2. Divide.
