the exact answer is 1,166 (and two thirds, but surprise, you can't have two thirds of a person) which I got by dividing 7000 by 6. Simple stuff.
If you need an estimate though you could say something like 1,150, with the explanation that you knew 6 would go into 6000 one thousand times and then into the remaining 1000 about 150 times since a close benchmark, 5, would go in about 200 times, and then just added 1000 times to 150 times to get 1,150
