I'm trying to round the divisor to the nearest whole number

198,200 divided by 4.033

The divisor is 4.033 because it divides 198,200. Rounded to the nearest whole number, it is 4 because 0 is less than 5, so the next highest (whole) place is unchanged.

For this case we have a division where:

198,200 is the dividend 4,033 is the divisor

If we want to round the divisor to the nearest whole number we have:

4.033 is equivalent to 4, because:

3 is less than 5, then we have 4.03

3 is less than 5, so we have 4.0 equivalent to 4.

Answer:

The divisor remains as 4, rounded to the nearest whole number.
