The simplified answer is 0.23
Prime numbers are only divisible by 1 or itself; the first few are are 2, 3, 5, 7, and 11.
The "divisor" in synthetic division is most conveniently the value of the zero of the binomial term. Here, that is x=5. You also need to make sure you include all of the coefficients in the "dividend", putting zero where terms are missing.
The appropriate choice is
