Allocate a total to 10 people based on shares

Hi,

I am looking to get a formula to split the amount in b12 evenly between 6 people on full share and split it between 4 others on 50% shares. Total of all splits should equate to the amount in b12 cell. For other events split will be different.

Could someone help with this?

Thanks,
