To estimate 868 divided by 28, you can round 868 to a nearby, more manageable number, such as 840. Then, divide 840 by 28, which is simpler; since 840 divided by 28 equals 30. This gives a rough estimate of 30 for the original division.
The front end estimate is 30. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 28.125 to 1 trillion, I would estimate it as 0.If I had to add 28.125 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 7, I would estimate it as 28, because 28/7=4. If I had to divide it by 10, I would estimate it as 30, because 30/10 = 3.

The front end estimate is 3000. But estimating a single number, in isolation and without context, is a complete waste of time. It all comes down to the context of what needs to be done with the number.If I had to add 2864 to 1 trillion, I would estimate it as 0.If I had to add 2864 to 0.0000000001, I would use the number as given, or possibly the front end estimate. If I had to divide it by 28, I would estimate it as 2856, because 2864/28 = 102. If I had to divide it by 10, I would estimate it as 2860, because 2860/10 = 286.
