When you divide a negative and a positive, you don't have to worry about the negative that much. Just divide like normal, and then add the negative at the end. However, if you divide a negative by a negative, it's double negative, and therefore positive. So in the case of -19 / 13, the answer would be negative.
Hope this helps! :)
