The best way to estimate a quotient using compatible numbers is to first understand how compatible numbers work. They are numbers that are close in value to the actual numbers and are easily added, subtracted or divided.
What's "best" depends on what you are going to use this for. You can take a calculator and do the exact calculation. Or you can round the numbers in a way that makes it easy to do the calculations in your head.
