It is because your calculator rounds the number \(\overline{0.66666666...}\) to the number \(0.66666667.\)
The same thing happens when you want to round the number \(\overline{0.316495...}\) to its hundredths. Instead of \(0.31\) you will get \(0.32,\) since the next digit after \(1\) is \(6\) that is \(\geq 5,\) so the rounding goes up.
