237 / 83 is 2.855421687
Now in this case I would round to the nearest hundredth. So I would look as the number in the hundredths place and look to the right of it and say, is it 5 or bigger, or is it less than 5. If it is less than 5 I would keep the number in the hundredths the same. If it is 5 or greater, I would add 1 to the number in the hundredths place. In this case it would be:
2.86
