In a fluid dynamics experiment, the drag coefficient $D$ of a specialized underwater drone is modeled as a function of its velocity $v$ (in m/s) by the expression:

$$D(v)=\frac{32v^2-14v+5}{4v-1}$$

The expression can be written in the form:

$$D(v)=Av+B+\frac{C}{4v-1}$$

where $A,B$, and $C$ are constants. State the value of $A$.
