C++ :

#include <bits/stdc++.h>
using namespace std;

int main(){
	string s1,s2;
	int c = 0;
	getline(cin,s1);
	getline(cin,s2);
	while(s2.find(s1) != -1){
		s2.replace(s2.find(s1),s1.size(),"");
		c++;
	}
	cout<<c<<endl;
}

Java :

import java.util.Scanner;

public class Main{
	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		String a= sc.nextLine();
		String b= sc.nextLine();
		sc.close();
		String arr[]=b.split(a);
		System.out.println(arr.length-1);
	}
}

Python :

a = input()
b = input()
print(b.count(a))
