Work Step by Step

We need to divide: $43\overline{)38,786}$ First, we estimate by rounding: $~~~~~~~~1000$ $40\overline{)40000}$ Next, we find the exact answer: $~~~~~~~~~902$ $43\overline{)38786}$ $~~~~~~\underline{387}$ $~~~~~~~~~~~~8$ $~~~~~~~~~~~~\underline{0}$ $~~~~~~~~~~~~86$ $~~~~~~~~~~~~\underline{86}$ $~~~~~~~~~~~~~~0$ We see that our estimate and exact answers are a bit off from each other.
