You would round 1,985,027 as you would with any other number. You achieve this by looking at the digit in the place value directly to the right of the place value you're rounding too. In your case, you're trying to round to the closest hundred thousand.
In 1,985,000, the 9 is the starting of the hundred thousands place value. If the value of the number directly to the right of it (8) is more than five, you round up. If it's less than five - round down.
Here, the ten-thousands place is an 8, which is greater than five. So you round up. 1,985,027 becomes 2,000,000. Because the place value can be no higher than a 9. So you're actually rounding to the next million because the hundred thousands place value has exceeded the highest number in the real number line (0, 1, 2, 3, 4, 5, 6, 7, 8, & 9).
