Proof step 16 from proof test-div-03 (previous step)

¬(1 % 10 = 0 ∧ 3 ≠ 0 ∧ 1 ≠ 0), div(mkDecimal(1, 0), mkDecimal(1000, 0), 0) * mkDecimal(1000, 0) = mkDecimal(1, 0) ⊦ mkDecimal(1 * mkDecimal(1000, 0).int, mkDecimal(1, 3).scale + mkDecimal(1000, 0).scale) = mkDecimal(1, 0), div(mkDecimal(1, 0), mkDecimal(1000, 0), 0) = mkDecimal(1, 3)
