The term of this problem is the same as the previous one, the only exception — increased restrictions.


-----Input-----

The first line contains two positive integers n and k (1 ≤ n ≤ 100 000, 1 ≤ k ≤ 10^9) — the number of ingredients and the number of grams of the magic powder.

The second line contains the sequence a_1, a_2, ..., a_{n} (1 ≤ a_{i} ≤ 10^9), where the i-th number is equal to the number of grams of the i-th ingredient, needed to bake one cookie.

The third line contains the sequence b_1, b_2, ..., b_{n} (1 ≤ b_{i} ≤ 10^9), where the i-th number is equal to the number of grams of the i-th ingredient, which Apollinaria has.


-----Output-----

Print the maximum number of cookies, which Apollinaria will be able to bake using the ingredients that she has and the magic powder.
