Just a math thing

Sometimes when i'm bored i play with numbers. Last time i took the smallest number that is able to divide by any digit (of course except zero) - it's 2520 if i'm right. And then i wrote results for dividing it by each digit and then i subtract any two that touch each other like this:

2520 : 1 = 2520
                     -   = 1260 
2520 : 2 = 1260        -   = 840
                     -   = 420         -   = 630
2520 : 3 = 840          -   = 210        -   = 504
                     -   = 210         -   = 126       -   = 420
2520 : 4 = 630          -   = 84          -   = 84         -   = 360
                     -   = 126         -   = 42         -   = 60         -   = 315
2520 : 5 = 504          -   = 42          -   = 24         -   = 45         -   = 280
                     -   = 84           -   = 18         -   = 15         -   = 35
2520 : 6 = 420          -   = 24          -   = 9           -   = 10
                     -   = 60           -   = 9           -   = 5
2520 : 7 = 360          -   = 15          -   = 4
                     -   = 45           -   = 5
2520 : 8 = 315          -   = 10
                     -   = 35
2520 : 9 = 280

I hope you see the pattern here. My question is, are patterns like this special or it will happen often if i do something like this?

I'm sorry, but I do not see the patter. Could you explain a bit?

It will happen often.
