If I assume that you're talking about 158 / 41 then my quick answer is yes, it is a good estimate. 4 times 41 is 164 which is closer to 158 than 3 times 41 (123) and 5 times 41 (205). Final summary: 4 is a good estimate for 158 / 41 because it is the closest whole number to the real answer.

Yes.
Yes. This is because 158 is approximately 160 and 41 is approximately 40. 160/40 = 4, therefore 4 is a good estimate of 158/41.

Yes, you round 158 to 160, and 41 to 40, and divide. Now, do the actual division (perhaps with a calculator), to see how close the estimate is. Practice with several similar divisions, to get a "feel" of how much rounding will result in how much of an error.
