We long divide as follows: \begin{array}{c|c@{\hspace{0pt}}c@{\hspace{0pt}}c@{\hspace{0pt}}c@{\hspace{0pt}}c@{\hspace{0pt}}c@{\hspace{0pt}}c@{\hspace{0pt}}c} \multicolumn{2}{r}{} & & & 7 & 7 & 1 & 6 & \\ \cline{2-8} 128 && 9&8&7&6&7&0 \\ \multicolumn{2}{r}{} & 8 & 9 & 6 &&&& \\ \cline{3-5} \multicolumn{2}{r}{} & & 9 & 1 & 6 &&& \\ \multicolumn{2}{r}{} & & 8 & 9 & 6 &&& \\ \cline{4-6} \multicolumn{2}{r}{} & & & 2 & 0 & 7 && \\ \multicolumn{2}{r}{} & & & 1 & 2 & 8 && \\ \cline{5-7} \multicolumn{2}{r}{} & & & & 7 & 9 & 0 & \\ \multicolumn{2}{r}{} & & & & 7 & 6 & 8 & \\ \cline{6-8} \multicolumn{2}{r}{} & & & & & 2 & 2 & \\ \end{array} So the remainder is $\boxed{22}$.
