how to divide two audio signals using simulink blocks. the audio signals contain floating points

I am implementing the some equations in simulink xilinx tool box, the equations are X(N) = [ x(n),x(n-1),x(n-2)...,x(n-p)] e(n) = d(n) – y(n)

g(n) =P(n-1) x*(n){ L +x T (n)P(n-1)x*(n)}-1

P(n) = P(n-1)-g(n)x T(n) P(n-1) w(n)=w(n-1)+e(n).g(n) y(n)=xT(n)w(n-1)

the p(n), g(n) are the recursive statements, they update each iteration.
