A trouble:twisted:, I believe you can simulate the divide using the invert operator and using the blend mode "color dodge" in the merge operator
link of tutorial?

it would have to function, you tried switch the inputs ?
the math of color dodge is divide for the inverse of the second input, if you invert the footage before the node you it will get a divide mode.
