Vim insert after specific number of delimiters
===

I am looking to make some code easier to read by taking something like this

    0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44 ....

and adding new lines to create increments of 8

    0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44, 0x44,
    0x44, 0x44 ....

Anyone know any vim magic that will allow me to this with specifically selected lines?
