Reorder expression in descending negtive power of a variable using Sage or Sympy

I have an expression

1/24*(8*(l + 1)*l + 5*(2*E*(l + 1)*l + 3)/E - 6)/E

I want to reorder it to the form

a * E**1 + b * E**0 + c * E**(-1) + d * E**(-2) + ...

sympy.simplify() gives me a close result.

from sympy import simplify
simplify(1/24*(8*(l + 1)*l + 5*(2*E*(l + 1)*l + 3)/E - 6)/E)

output

(6*E*l**2 + 6*E*l - 2*E + 5)/(8*E**2)

It didn’t combine 8*E**2.

What I expect is

3/4*l**2*E**(-1) + 3/4*l*E**(-1) - 1/4*E**(-1) + 5/8*E**(-2)

Is this possible?
