    Anyone know how I can do this CRC long division?

    11001 / 101110111010000

    Edit:
    I can do it, but how do I get started with this one? 11001 doesn't go into 10111 :holmes:

    Edit2:
    Divide 11001 by 101110? :holmes:
    Code:
    111111111111
    11001/101110111010000
            11001
             11100
             11001
               10111
               11001
                11101
                11001
                  10001
                  11001
                   10000
                   11001
                    10010
                    11001
                     10110
                     11001
                      11110
                      11001
                        r111
    I think... (Sorry, code tags aren't working properly )

    If I understand the formatting correctly,

    The first thing you did was 10111/11001 = 1 - How is that 1, when its equiv. to 23/25 which is <1 ? :holmes:

    No, don't think of it in the decimal sense - rely solely on the binary subtraction. Generally speaking in the field of error correction, the quotient you derive from the long division is irrelevant, all you're interested in is the remainder at the end.

    All you need to do to do the long division is:

    10111/110010...

    so you take the number you're dividing into (up to the number of digits you're dividing by):
    11001
    Then use a simple binary subtraction (bitwise XOR):
    11001
    10111 -

    We don't care about the quotient, so you can just write the result of the subtraction underneath (and we disregard any leading 0's as they're irrelevant)

    Thus:
    11001
    10111 -
    1110 ----- note that 1-1=0, but it's a leading 0 so it's ignored.

    You then drop down as many numbers as you need from the number you're dividing into, to make the next subtraction:

    11100

    You then repeat the process:

    11100
    10111 -

    etc.

    Do you follow?

    I understand the process but just got confused at the first step. Thanks.

    Why is it when you sign on for the day (and make no posts), your last quote was hours ago then a minute later, you have two new quotes. It's like picking up a mobile and suddenly receiving a text message. You feel like you've been endowed with godly powers. :proud:

    Also:

    Fail of the day
