The synthetic division table is:
$$ \begin{array}{c|rr}0&-5&-24\\& & \color{black}{0} \\ \hline &\color{blue}{-5}&\color{orangered}{-24} \end{array} $$The solution is:
$$ \frac{ -5x-24 }{ x } = \color{blue}{-5} \color{red}{~-~} \frac{ \color{red}{ 24 } }{ x } $$Step 1 : Write down the coefficients of the dividend into division table.Put the zero at the left.
$$ \begin{array}{c|rr}\color{blue}{0}&-5&-24\\& & \\ \hline && \end{array} $$Step 1 : Bring down the leading coefficient to the bottom row.
$$ \begin{array}{c|rr}0&\color{orangered}{ -5 }&-24\\& & \\ \hline &\color{orangered}{-5}& \end{array} $$Step 2 : Multiply by the number on the left, and carry the result into the next column: $ \color{blue}{ 0 } \cdot \color{blue}{ \left( -5 \right) } = \color{blue}{ 0 } $.
$$ \begin{array}{c|rr}\color{blue}{0}&-5&-24\\& & \color{blue}{0} \\ \hline &\color{blue}{-5}& \end{array} $$Step 3 : Add down last column: $ \color{orangered}{ -24 } + \color{orangered}{ 0 } = \color{orangered}{ -24 } $
$$ \begin{array}{c|rr}0&-5&\color{orangered}{ -24 }\\& & \color{orangered}{0} \\ \hline &\color{blue}{-5}&\color{orangered}{-24} \end{array} $$Bottom line represents the quotient $ \color{blue}{ -5 } $ with a remainder of $ \color{red}{ -24 } $.
