separating column by summations to a certain number

Hello there,

I've got a sheet with a large number of jobs (about 500) organized into 1 column where each one has a different operating time(in minutes). I want to organize them by day (approx. 480 minutes/day). Is there a combination of functions where I can sum the numbers in a column up to 480 and then have it start over as a way to group them?

Any suggestions would be very appreciated.
