Proof step 25 from proof fits-law-div-stronger (previous step)

i ≠ 0, ~(128 / i) = 128, b2i(by1) = ~ 128 ⊦ i = 0, i = ~1

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 26:
⊦ j ≠ 0 → i / ~ j = ~(i / j)
Proof step 27:
i ≠ 0, i ≠ 0, 128 / ~ i = 128, b2i(by1) = ~ 128 ⊦ i = 0, i = ~1

Rule argument

seq: ⊦ j ≠ 0 → i / ~ j = ~(i / j) subst: [j, i] → [i, 128] rotate: T spec: int-div inst: name: Div-right
