Hello again

I need a way of finding duplicates and counting them, for example say this is my data set:

1068349
887889
876220
1068349
1120092
909332
1078499
1012222

I would then like it to tell me for each individual number, so lets say the first at the top of the list "1068349" this as you can see is only duplicated once.
Id then like in the cell next to the right to tell me how many duplications there are like below:

1068349 2
887889
876220
1068349 2
1120092
909332
1078499
1012222

From there I can easily use the autowizard to sort them.

Is this possible?
I have a hell of a lot of data to get through!

Many thanks and kind regards,
Philip
