Explanation:
#color(blue)"Note that " 27=3xx9# So that dividing by 3 then 9 or 9 then 3 is the same as dividing by 27 but 'hopefully' a lot easier.
Using any available method you have for
#color(blue)"short division"#
#" I prefer "color(blue)"cancelling"# so will use that method.
#rArr13797/3=cancel(13797)^color(red)(4599)/cancel(3)^1#
#rArrcancel(4599)^(color(red)(511))/cancel(9)^1=511#
#"Thus " 13797-:27=511#
