It is wrong. In the second part of the division they take 1101 away from 1011 incorrectly.
Hello, I am trying to understand the following modulo 2 long division.
I understand that 1101 goes into 1111, so you write a 1 on the top.
The next stage after 'XOR'ing is to bring down the 1.
Now, 1101 does not go into 101, so you write a 0 at the top. So far so so good.
Now you bring down another 1 and 1101 still does not go into 1011, so how come they wrote a 1 in the third position at the top ? Shouldn't that be a zero ?
If someone could please explain where I am going wrong, I would most grateful.
I suspect a typo in the problem.Code:1 0 0 1 1 0 1 1 ----------------------- 1 1 0 1 | 1 1 1 1 1 1 0 1 0 1 0 1 1 0 1 ------- 1 0 1 1 0 1 1 0 1 --------- 1 0 0 1 1 1 1 0 1 -------- 1 1 0 0 1 1 1 0 1 --------- 1 1 0 0 0 1 1 0 1 --------- 1 0 1 1
