### 2.31.8 Division in ℤ/pℤ or in ℤ/pℤ[x] : `/`

`/` divides two integers in ℤ/pℤ or two polynomials A and B in ℤ/pℤ[x].
For polynomials, the result is the irreducible representant of the fraction A/B in ℤ/pℤ[x].
For integers in ℤ/pℤ, input :

`5%13/2% 13`

Since 2 is invertible in Z/13ℤ, we get the output :

`-4%13`

For polynomials with coefficients in ℤ/pℤ, input :

`(2*x```^```2+5)%13/(5*x```^```2+2*x-3)%13`

Output :

`((6%13)*x+1%13)/((2%13)*x+2%13)`
