Proof step 3 from proof div-succ (previous step)

m % n + 1 = n ⊦ (m + 1) / n = m / n + 1, n = 0

User applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
n ≠ 0 ⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n
Proof step 5:
n0 + 1 = n, m = m0 * n + n0, n0 < n ⊦ (m + 1) / n = m0 + 1, n = 0

Rule argument

spec: <toplevel> name: div-elim seq: n ≠ 0 ⊦ m0 = m / n ∧ n0 = m % n ↔ m = m0 * n + n0 ∧ n0 < n subst: [m, n, m0, n0] → [m, n, m0, n0] flags: <rotated> <all paths>
