What is the percentage of historical works that have not fewer than five scenes in the 1500s?
historical works refers to GenreType = 'history'; have not fewer than five scenes in the 1500s refers to count(Scene) > = 5 and DATE > = 1500 AND DATE < = 1599; percentage = divide(count(works.id) where GenreType = 'history' and count(Scene) > = 5, count(works.id) ) as percentage
SELECT CAST(( SELECT COUNT(T1.id) FROM works AS T1 INNER JOIN chapters AS T2 ON T1.id = T2.work_id WHERE T1.GenreType = 'History' AND T1.DATE BETWEEN 1500 AND 1599 GROUP BY T1.id HAVING COUNT(T2.Scene) >= 5 ) AS REAL) * 100 / COUNT(id) FROM works WHERE GenreType = 'History' AND DATE BETWEEN 1500 AND 1599
