divide 3d matrix (840,64,1536) by 1d matrix (1536,1)

Hello community !

I need help for a simple problem:

I have a matrix A of Dimension (840,64,1536) and a matrix B of dimension (1536,1)

I need to divide each set A(840,64, i ) by the i-th value of B B(i).

I could do a clumpsy for loop, but would like a smarter approach.

Thanky you for your support!

Florian.
