Logic:

1) Take any natural number say..10.

2) divide by 2, and find remainder...repeat the same process until u get 0.

divisor number remainder

2 10 (0)

---------------------------------

2 5 (1)

----------------------------------

2 2 (0)

----------------------------------

2 1 (1)

----------------------------------

0

3) Now look at the remainder pattern from bottom to top, ie. 1010 which is an equivallent for decimal number 10.
