Answer:
HELLOOOO
Alr lets start with steps by dividing by 2 again and againn..
265 / 2 = 132 ( rem = 1 )
132 / 2 = 66 ( rem = 0 )
66/2 = 33 ( rem = 0 )
33/2 = 16 ( rem = 1 )
16/2 = 8 ( rem = 0 )
8/2 = 4 ( rem = 0 )
4/2 = 2 ( rem = 0 )
2/2 = 1 ( rem = 0 )
1/2 = 0 ( rem = 1 )
now write all the remainders from bottom to up
100001001
is ur ans :)))
