Proof step 17 from proof mod-zero-one (previous step)

0 ≤ i, 0 ≤ i0, 0 < j ⊦ (i % j + i0 % j) / j ≥ 0, (i % j + i0 % j) / j = 1, (i % j + i0 % j) / j = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 18:
(i % j + i0 % j) / j < j, (i % j + i0 % j) / j < 0, 0 < j, 0 ≤ i0, 0 ≤ i, (i % j + i0 % j) / j + 1 < j ⊦ (i % j + i0 % j) / j = 0, (i % j + i0 % j) / j = 1
