  quotient≢0       : m ∣ n → .{{NonZero n}} → NonZero quotient
  
  m|n⇒n≡quotient*m : m ∣ n → n ≡ quotient * m
  m|n⇒n≡m*quotient : m ∣ n → n ≡ m * quotient
  quotient-∣       : m ∣ n → quotient ∣ n
  quotient>1       : m ∣ n → m < n → 1 < quotient
  quotient-<       : m ∣ n → .{{NonTrivial m}} → .{{NonZero n}} → quotient < n
  n/m≡quotient     : m ∣ n → .{{_ : NonZero m}} → n / m ≡ quotient

• Added new proofs in Data.Nat.Properties:

  m≤n+o⇒m∸n≤o : ∀ m n {o} → m ≤ n + o → m ∸ n ≤ o
  m<n+o⇒m∸n<o : ∀ m n {o} → .{{NonZero o}} → m < n + o → m ∸ n < o
  pred-cancel-≤ : pred m ≤ pred n → (m ≡ 1 × n ≡ 0) ⊎ m ≤ n
  pred-cancel-< : pred m < pred n → m < n
  pred-injective : .{{NonZero m}} → .{{NonZero n}} → pred m ≡ pred n → m ≡ n
  pred-cancel-≡ : pred m ≡ pred n → ((m ≡ 0 × n ≡ 1) ⊎ (m ≡ 1 × n ≡ 0)) ⊎ m ≡ n

• Added new functions in Data.String.Base:

  map : (Char → Char) → String → String
