You can divide by zero with casting. Why?

Hi. There is a task here on CodeGym that requires to change cast operators to get a desired result. I've solved it but it contains something that I simply don't understand.

double f = (char) 1234.15;
long d = (int) (f / c);
System.out.println(d);

The 'd' will yield 2147483647 if 'f' is of type double. If I change to int, it throws ArithmeticException.

int f =  1234;
long d = (int) (f / c);
System.out.println(d);

Why? Can you divide by zero if it's not an int or when you're casting it?
