find multiple sets of consecutive numbers in a single cell

[richardsmith1982]

Hi all,
I've tried searching lots of places for help on this, but cannot find what I need....

I've been given the most unhelpful file and need to try to decipher it to create useful reports.
I have lots of data in a single cell, and lots of other cells on the same row contain a similar story.
I think my aim is to make a new sheet and use this main page as an overview, with the contents of each cell having their own sheet.

I'm looking for a way to find the first instance of a number and display all consecutive numbers; a way to find the second instance of a number and display all consecutive numbers, etc. I have seen how to find the nth value, but I need all consecutive numbers to count as one instance. Some of the consecutive numbers are single digits, others are five digits.
I think at this point I may even take just using a newline as a cell break (copy and paste but the paste puts the single cell in to five according to the number of linebreaks)

Here is the contents of a single cell:

MAILCHIMP: 502 subscribersGOOGLE DOCS: 502 plus those who have unsubscribed but havent't yet been removed from google doc.
**Source of google doc info: webiste enquiries
BRUSHFIRE: 22
EMAIL:200-250 all data from formstack, email enquiries. All info still on work laptop. All sitting in a follow up folder on lap top.
FORMSTACK: 150

Has anyone experienced this before (and held back from throwing their boss out the window)?
Can anyone help?

Thanks!
