Proof step 2 from proof div-am-rew (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 3:
⊦ 0 < j ∧ 0 ≤ i → (i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ 0 ≤ j0 ∧ j0 < j ∧ 0 ≤ i0)
Proof step 4:
i1 = i2 * j + j0 ∧ 0 ≤ j0 ∧ j0 < j ∧ 0 ≤ i2, 0 ≤ i, 0 ≤ i0, 0 < j, 0 ≤ i1 ⊦ (i + i0 * i1) / j = (i + i0 * j0) / j + i0 * i2

Rule argument

spec: int-div inst: name: div-elim-pospos seq: ⊦ 0 < j ∧ 0 ≤ i → ( i0 = i / j ∧ j0 = i % j ↔ i = i0 * j + j0 ∧ 0 ≤ j0 ∧ j0 < j ∧ 0 ≤ i0) subst: [i, j, i0, j0] → [i1, j, i2, j0] flags: rewrite, current
