concatenated matrix - factoring out a matrix coefficient

A, B and C are MxN matrices. I construct a matrix D in the following way:
D = [A./C, B./C]
It is inviting to bring out the coefficient ./C
D = [A, B]./C
however this change conflicts Matlab rules [A, B] being an Mx2N matrix and ./C being an MxN matrix.
Is there a convenient way in Matlab to factor out a matrix coefficient?

D = [A, B]./[C, C]
which isn't more convenient than the initial expression! Depending the context, you can REPELEM or REPMAT C as many times as necessary if this is not always 2, but there is no easy shortcut or simple automatic expansion that I can think of.
