Proof step 2 from proof div-elim (previous step)

⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n, n = 0

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ n ≠ 0 → m = m / n * n + m % n

Rule argument

spec: inst: name: Moddef seq: ⊦ n ≠ 0 → m = m / n * n + m % n subst: [n, m] → [n, m] flags: current, []
