The nearest hundred thousand would give you zeros after the comma in 176,257
If the number to the right of the comma in this case the "2" is 4 or less than you don't round the 6 up. If the "2" is 5 or greater than you round the 6 up by one number.
For example : 123,557 gives us 124,000
but 123,337 gives us 123,000
Therefore our answer is 176,000
