Proof step 16 from proof pot-mod-add-zero (previous step)

i % j = 0, 0 ≤ j, 0 ≤ i1 ⊦ (i + i0 * j ^ i1 * j) % j = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: int-div inst: name: modex seq: j ≠ 0 ⊦ i % j = 0 ↔ (∃ j0. i = j0 * j) subst: [j, i] → [j, i] flags: rewrite
