Hi,
I'm trying to work out a binary division problem
1100 / 101010101010111
Here is what I have so far but I'm not sure if I'm doing it correctly
and I'm suppose to continue the division until there is only a
remainder left
110
_______________ _______
1100 [ 101010101010111
1100
_______________
1101
1100
_______________
01010
1100
_____________
110
I'm not sure if I'm doing this correctly and I don't really have a way
of checking if I'm doing it right. Does anyone know of a simple web
calculator that I can check against my answer or if someone could run
through this example with me, that would be great. thank you

The integer quotient is 0, as always when the divisor is greater
than the dividend, for positive operands. The remainder is 1100.

Does it have to be on the web? Since you're appear to be posting from
Windows, I'd suggest the Windows calculator, in scientific mode.

Windows calculator does not give the correct solution.
An example that I worked out with the correct solution is not the same
as the windows calculator is giving
1001 / 101110000
Solution = 101011 with Remainder of 011 and the remainder is what I'm
interested in.

There's no way that the quotient to that division can be 101011.
That's as silly as saying that 1234 / 123456789 = 456789.
Dividing a small number by a large number yields 0, with the
small number as remainder.

This is an example on calculating the remainder in use with CRC. Maybe
I might of not explained it properly, but that is the correct solution
and this is using binary division to get a quotient and specifically
interested in the remainder value because that is the extra amount of
bits tacked onto a file for checksum.

Why didn't you use the 'MOD' button on the Windows calculator?
(I am lucky to know Forth, '/MOD' gives the quotient and remaider at once.)

The mod button does not give you the correct solution. It just returns
the original value that you're trying to use to divide into.

Of course, the quotient is zero, so the remainder is the dividend, like Ben
Pfaff said. Simple maths.
