Proof step 11 from proof mkDecimal-maxScale-le (previous step)

¬((i / 10 ^ maxScale(i)) % 10 = 0 ∧ abs(j) - maxScale(i) ≠ 0 ∧ i / 10 ^ maxScale(i) ≠ 0), maxScale(i) ≤ abs(j) ⊦ i / 10 ^ maxScale(i) = i / 10 ^ maxScale(i) ∧ abs(j) = mkDecimal(i / 10 ^ maxScale(i), abs(j) - maxScale(i)).scale + maxScale(i)
