To round to the nearest 100,000, you drop the last five digits - i.e., replace them by zeros. If the leftmost digit is a 5, 6, 7, 8 or 9, you then add one to the first (rightmost) digit that you didn't drop.
The same procedure applies to rounding in general; except for the number of digits dropped.
