2. Step 2: Then divide it by the divisor and write the answer on top as the quotient.
3. Step 3: Subtract the result from the digit and write the difference below.
4. Step 4: Bring down the next number (if present).
5. Step 5: Repeat the same process.

## What are the 5 steps of long division?

## How do you divide and verify in division algorithm?

On dividing we get a quotient as \[3{y^2} + 2y + 2\]and remainder as \[4{y^2} + 25y + 4\]. Therefore, the given equation is verified using the division algorithm. It is given that the dividend is \[4{y^3} + 8{y^2} + 8y + 7\]. The divisor is given as \[2{y^2} – y + 1\].

## What division algorithm says?

A division algorithm is an algorithm which, given two integers N and D, computes their quotient and/or remainder, the result of Euclidean division.

## How do you find the quotient using the division algorithm?

When we divide a positive integer (the dividend) by another positive integer (the divisor), we obtain a quotient. We multiply the quotient to the divisor, and subtract the product from the dividend to obtain the remainder. Such a division produces two results: a quotient and a remainder.

## How do you verify multiplication?

Add the digits of the product that you originally answered and reduce to a single digit. For example, if you obtained the answer 221,122 from multiplying 506 times 437, then you would add 2, 2, 1, 1, 2 and 2 to get 10.
