The polynomial long division calculator divides two polynomial expressions to find the quotient and remainder. This polynomial division calculator with steps provides detailed calculations for long polynomial division.

## What Is Polynomial Long Division?

In algebra, the long division of polynomials is an algorithm for dividing the polynomial, where a polynomial is divided by the other polynomial of the same or lower degree.

It can be done easily with the assistance of a dividing polynomials calculator with steps because it separates complex division problems into smaller ones.

## How To Do Polynomial Long Division?

Let us resolve an example to clarify the technique of long division with polynomials!q

Find the quotient and the remainder with long division, where the dividend is $$2x^3 – 3x^2 + 13x – 5$$ and the divisor is x + 5.

### Solution:

$$\require {enclose} \begin {array} {rrrrrr} \\x + 5&\phantom {-} \enclose {longdiv} {\begin {array} {cccccc} 2x^3 & – 3x^2 & + 13x & – 5\end {array}} \end {array}$$

#### Step 1:

Divide the leading term of the dividend by the leading term of the divisor:

$$\space \dfrac{2 x^{3}}{x} = 2 x^{2}$$

Multiply it by the divisor:

$$\space 2 x^{2} (x + 5) = 2 x^{3} + 10 x^{2}$$

Subtract the dividend from the obtained result:

$$\space (2 x^{3} – 3 x^{2} + 13 x – 5) – (2 x^{3} + 10 x^{2}) = – 13 x^{2} + 13 x – 5$$

#### Step 2:

Repeating the steps again:

$$\space \dfrac{- 13 x^{2}} {x} = – 13 x$$

$$\space – 13 x(x + 5) = – 13 x^{2} – 65 x$$

$$\space (2 x^{3} – 3 x^{2} + 13 x – 5) – (- 13 x^{2} – 65 x) = 78 x – 5$$

#### Step 3:

$$\space \dfrac{78 x}{x} = 78$$

$$\space 78(x + 5) = 78 x + 390$$.

$$\space (2 x^{3} – 3 x^{2} + 13 x – 5) – (78 x + 390) = -395$$

#### Result Table:

$$\require {enclose} \begin{array} {rlc} \phantom{x + 5}&\phantom{\enclose{longdiv}{}-}\begin{array}{rrrrrr} 2 x^{2} & – 13 x & + 78&\end{array}&\\x + 5&\phantom{-}\enclose{longdiv}{\begin{array}{cccccc}2x^3 & – 3x^2 & + 13x & – 5\end{array}}\\&\begin{array}{rrrrrr}-\\\phantom{\enclose{longdiv}{}} 2 x^{3} & + 10 x^{2}\\\hline\phantom{\enclose{longdiv}{}}&- 13 x^{2} & + 13 x & – 5 \\&-\\\phantom{\enclose{longdiv}{}}&- 13 x^{2} & – 65 x\\\hline\phantom{\enclose{longdiv}{}}&&78 x & – 5 \\&&-\\\phantom{\enclose{longdiv}{}}&&78 x & + 390\\\hline\phantom{\enclose{longdiv}{}}&&&-395 \\\\\phantom{\enclose{longdiv}{}}&&&\end{array}&\begin{array}{c}\\\phantom{} \end{array}\end{array}$$
So, the quotient is $$2x^2−13x+78$$, and the remainder is −395

$$\dfrac{2 x^{3} – 3 x^{2} + 13 x – 5}{x + 5} = {2 x^{2} – 13 x + 78+\dfrac{(-395)}{x + 5}}$$

You could try a polynomial long division calculator with remainders to attain the complete result table for quotient and remainder.

However, an online Synthetic division to find zeros calculator will allow you to determine the reminder and quotient of polynomials using the synthetic division method.
