DHIMAN MANDAL  (11 years ago)

if we divide 7 by 8 then remainder =7
and if we divide 77 by 8 then remainder=5
if we divide the 777 by 8 then remainder will be=1
and for next all number if we divide the number by 8 remainder =1
so toatal remainder=7+5+(1*198)=210
now if we divide the 210 by 8 then remainder will be 2 ...
so finally remainder will be 2(ans)
