Relax. You're not completely lost.
The car has to cover 600 km. That's 600,000 meters.
If it could only move at 1 meter per second, it would take the car 600,000 seconds to cover the distance. (almost a week !)
But it can move faster than that. In fact, it can cover 80 meters every second.
How many times does it need to do 80 meters, in order to cover the whole 600,000 ? That's how many seconds it'll take.
That's division.
