When you have an actual functioning competitive market the money you bring in correlates with the value of the service you provide, so it makes perfect sense to be happy about the money the new surgical center is bringing in. That means it’s useful.
The problem is that the health care market is regulated and subsidized in so many ways, many of them conflicting with each other, that competition is very limited and price discovery is reduced to “whatever the patient (and their insurance) can afford to pay” since they can’t go anywhere else. Fix that and there won’t be any reason for hospital owners or employees to feel guilty about making money.
In general integer division is implemented using a form of long division, in binary. There is no base-10 arithmetic involved. It’s a relatively expensive operation which usually requires multiple clock cycles to complete, whereas dividing by a power of two (“bit shifting”) is trivial and can be done in hardware simply by routing the signals appropriately, without any logic gates.
