Explicação passo a passo:

$\begin{matrix}\space\space&1&8&6\\ -&0&4&9\end{matrix}$

$\begin{matrix}\space\space&\space\space&\textbf{7}&10\\ \space\space&1&\textbf{\linethrough{8}}&6\\ -&0&\textbf{4}&9\end{matrix}$

$\begin{matrix}\space\space&\space\space&7&\textbf{16}\\ \space\space&1&\linethrough{8}&\textbf{\linethrough{6}}\\ -&0&4&\textbf{9}\end{matrix}$

$\frac{\begin{matrix}\space\space&\space\space&7&\textbf{16}\\ \space\space&1&\linethrough{8}&\textbf{\linethrough{6}}\\ -&0&4&\textbf{9}\end{matrix}}{\begin{matrix}\space\space&\space\space&\space\space&\textbf{7}\end{matrix}}$

$\frac{\begin{matrix}\space\space&\space\space&\textbf{7}&16\\ \space\space&1&\textbf{\linethrough{8}}&\linethrough{6}\\ -&0&\textbf{4}&9\end{matrix}}{\begin{matrix}\space\space&\space\space&\textbf{3}&7\end{matrix}}$

$\frac{\begin{matrix}\space\space&\textbf{\space\space}&7&16\\ \space\space&\textbf{1}&\linethrough{8}&\linethrough{6}\\ -&\textbf{0}&4&9\end{matrix}}{\begin{matrix}\space\space&\textbf{1}&3&7\end{matrix}}$

$=137$
