Rewrite the expression in long division form .

Use division to write the divisor so it has the coefficient of 1.

Divide the numerator and denominator by 1.

Simplify the numerator and denominator.

Write the terms of the dividend so that the degrees of the terms are in descending

order. Then write just the coefficients as shown below.

Bring down the first coefficient.

Multiply the first coefficient by r: .

Write the product under the second coefficient.

Then add the product and the second coefficient:  0 + 3 = 3

Multiply the sum coefficient 3, by r: Write the product under the next 

Write the product under the third coefficient

Then add the product and the third coefficient:  0 + 9 = 9

The remainder is the last entry in the last row. Therefore, R = 0

The numbers along the bottom row are the coefficients of the quotient.

Start with the power of y that is one less than the degree of the dividend.

The result of division is

The result of division is .
