Answer
$\ \ \ 526\underline9$
$\underline{-2\underline385}$
$\ \ \ 28\underline84$
Work Step by Step
$\ \ \ \ \ \ \ \ \ \ \Rsh9-5=4$
$\ \ \ 52\,6\underline{ }$
$\underline{-2\underline{ }85}$
$\ \ \ 2\,8\underline{ }4$
$\ \ \ \ \ \ \ \hookrightarrow16-8=8$
$\ \ \ 5\overset1/\!\!2\,\overset{16}6\underline{9}$
$\underline{-2\underline{ }\,8\,5}$
$\ \ \ 2\,8\,\underline{8}\,4$
$\ \ \ \ \ \ \hookrightarrow51-23=28$
