Maths Challenge

Wrire a program to recursively sum the digits of a number until there is only one number.
For example the number 1654876 is summed to 1+6+5+4+8+7+6 = 37, which is summed to 3+7 = 10, which is summed to 1+0 = 1.
As a follow-up.  Are reduced sum of digids (1- 9) evenly distributed, equally likely or are some more common for a large number of integers?  Are there any other patterns or comclusions that you can find?
