Create Function To Selects Data From ABC Column And Put Into New Columns For Each Step

Is this possible? If

A B C
0 0 0
0 0 0
1 4 5
2 4 8
0 0 0
0 0 0
0 0 0
2 6 9
8 9 3
3 5 6
0 0 0

In the raw data, the 0s split up the data into different steps. I am trying to create a function that selects the data from the ABC column and puts it into new columns for each step. I.e:

New Columns with:
1 4 5
2 4 8

and
2 6 9
8 9 3
3 5 6

In the raw data files, there will be 10 steps, with a varying length of data.
