#87.33/2.2 xx10/10 = 873.3/22#
Use long division:
#color(white)(xxxx)color(blue)(3)color(red)(9)color(brown)(.6) " rem " 21#
#22|bar(873.3) " "larr " " 87div 22 = color(blue)(3)#
#color(white)(xxx)ul66darr " "larr " "3xx22 =66#
#color(white)(xxx)213" "larr " subtract " 3darr (213div22 =color(red)(9))#
#color(white)(xxx)ul198darr" "larr " "9xx22=198#
#color(white)(xxxx)153" "larr " subtract " 3darr (153div22 =color(brown)(6))#
#color(white)(xxxx)ul132 " "larr " "6xx22 =132#
