 First, we divide 11 by 2 to find the least significant digit
(the rightmost digit). Since 1 is our remainder, the least significant
digit in our answer is 1.

11 / 2 = 5
R 1 
Answer:
? ? ? 1 

 Next, we take the result of the previous division (5) and divide
by 2 again. Since 5 divided by 2 leaves a remainder of 1, the
next digit of our answer is 1.

5 / 2 = 2 R
1 
Answer:
? ? 1 1 

 Again we take the result of the previous division (2) and divide
by 2. This time our division does not have a remainder, so we
write a 0 as the next digit of our answer.

2 / 2 = 1 R
0 
Answer:
? 0 1 1 

 One more division by 2 gives us the most significant digit (the
leftmost digit) of our answer. Since 2 will not divide 1, our
result is 0 with a remainder of 1. We know we are done when we
get 0 as the result of our division.

1 / 2 = 0 R
1 
Answer:
1 0 1 1
