Problem Statement

We have a truck, which can carry at most $N$ kilograms.

We will load bricks onto this truck, each of which weighs $W$ kilograms. At most how many bricks can be loaded?

Constraints

• $1\\leq N,W \\leq 1000$
• $N$ and $W$ are integers.

Input

Input is given from Standard Input in the following format:

$N$ $W$

Output

Print an integer representing the maximum number of bricks that can be loaded onto the truck.

Sample Input 1

10 3

Sample Output 1

3

Each brick weighs $3$ kilograms, so $3$ bricks weigh $9$ kilograms, and $4$ weigh $12$ kilograms.

Thus, we can load at most $3$ bricks onto the truck that can carry at most $10$ kilograms.

Sample Input 2

1000 1

Sample Output 2

1000
