I know I could go through a long tortured procedure where I assign the magnitude and angle of V to different variables and use them to calculate the real and imaginary components of V.  That is way over the top for what I want to do.  What is the EASIEST way to accomplish this division?

Nothing stops you from writing it. But, no. There is
no such tool.
