1. Natural Divisibility and an Explicit Multiplier Witness

Natural numbers include 0. Every a divides 0; 0 divides b exactly when b=0. Divisibility witnesses are natural-number multipliers, not approximate quotients. a=0, b=0. Give (a, b, a divides b?, natural witness k for b=a*k or does-not-exist). For 0 divides 0 choose k=0, without claiming uniqueness.

View answer and explanation

(0, 0, Yes, 0)

Handle a=0 before division; otherwise require zero remainder and retain the exact natural quotient. Exact finite/synthetic checks are not new general formal Evidence. The exact result, retaining the requested order, is (0, 0, Yes, 0).
