Proof step 8 from proof alignup-le-is-aligned (previous step)

m % n = 0, m < (m0 % n = 0 ⊃ m0;n * m0 / n + n), m0 < n * m0 / n + n, m0 ≤ m ⊦ m0 % n = 0, n = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
m % n = 0, m < n * m0 / n + n, m0 < n * m0 / n + n, m0 ≤ m ⊦ m0 % n = 0, n = 0

Rule argument
