Proof step 2 from proof nummult-modle-01 (previous step)

i % j = 0, j < i, 0 < j ⊦ i * i0 ≤ j * j0 ↔ i / j * i0 ≤ j0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
i % j = 0, 1 < i, j < i, 0 < j, 0 < i ⊦ i * i0 ≤ j * j0 ↔ i / j * i0 ≤ j0

Rule argument
