Is there a way to cut part of the text in one cell and put it into another?

For example, if I have a dropdown list in cell B3 that includes both an
account number and an account name. I would like cell C3 to take the account
name from cell B3 so all that's left in B3 is the account number.

I know there is an easier way to do this by splitting up the name and number
then using a vlookup for C3 but we need to see both the account name and
number n the dropdown list in order to decide which to use.

Is this possible?

Thnks very much
