I want to divide 2 binary polynomials with matlab.

As in the attached picture.

I have the following code, but unfortunately this does not work because it does not calculate binary.

g = poly2sym([1 0 1 1]);

x = poly2sym([1 0 0 0])

u1 = poly2sym([1 0 0 0])

[q,r] = deconv(sym2poly(x *u1) ,sym2poly(g))

How could I do this?

I understand that you are trying to perform Binary Polynomial Division ( Modulo Division of Polynomials ) . To get the expected result, gfdeconv command should be used instead of deconv with some modifications in writing polynomials as shown

g = x^3 + x + 1 = 1 + x + x^3 = [1 1 0 1]

The following code snippet helps you for better understanding of using the command

g = [1 1 0 1] % g = 1 + x + x^3

gfpretty(g)

x1 = [0 0 0 1] % x1 = x^3

gfpretty(x1)

u1 = [0 0 0 1] % u1 = x^3

gfpretty(u1)

[q,r] = gfdeconv(conv(x1,u1) ,g) %q -> queotient, r -> remainder

gfpretty(q)

gfpretty(r)

Refer to the below documentation link for more information on gfdeconv and gfpretty

Hope the query is resolved.
