the "th" family is a little confusing but you look and find the millionth place. It's basically backwards.
0 is tenths
6 is hundredths
7 is thousandths
3 is ten-thousandths
5 is hundred-thousands
9 is millionths
the number next to it is a 9 (rule round up if it's greater than 5)
since the number is a 9 you have to round up even one more making the 5 a 6
3.06736
