Removing some data from a QR Code Field and entering it into other fields

Removing some data from a QR Code Field and entering it into other fields

Hi 
I am scanning a QR code into a field that consists of the test data  "01/2347/011  02  242"

I would like to extract the "01/2347/011" part of the QR Code field test data  and have it entered into a field in the same QR Code table named part number
i would like to extract the "02" part of the QR code field test data and have it entered into a field on the same QR Code table called operation number 
I would like to extract the "242" part of the QR code test data and put it into a field in the same QR Code table named quantity

Please can you explain how I do this ?

Thanks

Sam
