Flat out dividing the weight doesn't work for a few reasons, starting with elongated systems and torque. Lets take an extreme here, and assume the character is using something like an over sized sledgehammer, which they can do compliments of super strength. Now, say that the sledgehammer ends up with the middle on top of a narrow surface somehow, more or less at rest - this isn't hugely plausible, but it . Regardless of how strong the character is, if the hammer is heavier than they are the end will move down, they will be pulled up, and mass is going to end up far more relevant than strength.

Now, that's obviously somewhat contrived, but the principle remains the same at more plausible levels. Super strength doesn't really solve issues with extreme mass particularly well, and that mass does create big forces if it is being thrown around, at which point problems along the lines of frictional forces between the wielder and the ground not being sufficient due to their low weight suddenly arise. They might be able to slam a heavy vehicle with a ridiculously heavy club, but they will slide around on impact, which is profoundly unhelpful. As such, even with very dramatic strength weight increase is probably not the best idea, particularly if it is on something that will move a lot.
