6s into 6 = 1
6s into 4 = 0 - carry the 4 over to the next space
6s into 40 = 6 remainder 4 - carry the 4
6s into 40 = 6 remainder 4 - carry the 4
4 will become repeatedly carried (an infinite number of times) so we call it a recurring number. This can be shown by a number (in this case 6) with a dot above it.
(18 + 46)/6 = 10.666... or 10.67
