You're dividing 8 into 5000. If you were dividing 8 into 8000, it would go in 1000 times. Half of 8000 is 4000, so half of 1000 is 500. So it's between 500 and 1000. 5000 is one-fourth more than 4000, so add one-fourth of 500, which is 125, to 500 to get 625. There is 80 more than 5000, which divided by 8 gives 10, which added to 625 gives 635. And 4 is one-half of 8, so the answer is 635.5.
Now I went all the way through the problem. You should estimate to the nearest thousand, hundred, ten, or one depending on what your teacher asks for.
