For clarity, can you share your example schema definition, along with test data indicating the desired output please?

One suggestion would be to handle the case for 0 within your computed column definition and assigning NULL in it's place.

create table testTable

(

ValueOne int,

ValueTwo int,

Calcuation as ValueOne/case when ValueTwo = 0 then null else ValueTwo end

)

insert into testTable(ValueOne,ValueTwo) values(1,1)

insert into testTable(ValueOne,ValueTwo) values(1,0)

select * from testTable
