Theorem quoremnn0ALT 12656

Description: Alternate proof of quoremnn0 12655 not using quoremz 12654. TODO - Keep either quoremnn0ALT 12656 (if we don't keep quoremz 12654) or quoremnn0 12655. (Contributed by NM, 14-Aug-2008.) (Proof modification is discouraged.) (New usage is discouraged.)

Hypotheses

Ref	Expression
quorem.1	⊢ 𝑄 = (⌊‘(𝐴 / 𝐵))
quorem.2	⊢ 𝑅 = (𝐴 − (𝐵 · 𝑄))

Assertion

Ref	Expression
quoremnn0ALT	⊢ ((𝐴 ∈ ℕ0 ∧ 𝐵 ∈ ℕ) → ((𝑄 ∈ ℕ0 ∧ 𝑅 ∈ ℕ0) ∧ (𝑅 < 𝐵 ∧ 𝐴 = ((𝐵 · 𝑄) + 𝑅))))
