The problem is that 1/4 in T-SQL is not a literal meaning 0.25. It is an expression meaning integer 1 diveded by integer 4. Thus the result is an integer. Thus 0.
You need to modify this expression to a wider type. It's pretty simple, while not obvious: 1 / 4.0.

So this should do it:

``````UPDATE ExactCostLaborTimings_WorkingTbl_Granular
SET    DividingFactor = 1/4.0;
``````

It's probably treating 1 and 4 as integers, losing precision, so the result is rounded to 0.  Adding a decimal, like with 0.25 or 1/4.0 implicitly converts the values to a data type that preserves the fractional number.  You could also use an explicit cast to do the same thing CAST(1 as decimal) / CAST(4 as decimal)
