Your system  results my code as wrong. Why ?

 

import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int first = scanner.nextInt();
        int second = scanner.nextInt();
        int divider = scanner.nextInt();
        int vysledok = 0;
        while (first <= second) {
            if (first % divider == 0) {
                vysledok++;
                first += divider;
            } else {
                first += divider;
            }
        }
        System.out.println(vysledok);
    }
}
