Command Line – How to go through folders in a directory and input to a list and then print

I have directories named 3 through 8. Each directory contains a file called FILE. I have to enter a number from this file as follows:

grep Elapsed FILE|egrep -o "[0-9]+.[0-9]+"

So, in the end, I want to print two columns as directory names egrep Issue like:

3 273.011
4 452.047 

Many thanks for your help!
