Hmmm, I don't use assembly any more. I've settled on c++ (and java when forced into it). It's nice to know especially in that you get a real tight handle on what a CPU actually is. But I'm not sure how to go about learning it these days. The only thing I did on my ZX81 was use it's so called graphics mode to plot successive shrinking squares (using "fast mode" where it turned the graphics off for speed) assembly was the only way to do anything on the XZ81,C64. You needed it a little on the Amiga and MS/DOS graphics (with C doing most the work). On Win95 I used it for a hi res timer (only a couple lines). But haven't used it since. If I were to dig in now, I miiiight start with the C++ compiler's assembly listings. Look at your C++, look at the unoptimized assembly the compiler generates and see how they equate. Google will find quite a few sites of people still using 80x86 assembly I think. Good luck to ya.
