Find closest multiple of $54$ to $483$. We see that $8 \times 54 = 432$ is the nearest. Now subtract $432$ from $483$ to get reminder $51$. Add $8$ to quotient.
Find closest multiple of $54$ to $511$. We see that $9 \times 54 = 486$ is the nearest. Now subtract $486$ from $511$ to get reminder $25$. Add $9$ to quotient.
Since $25$ is less than $54$, stop the division. The reminder is $25$. The topmost line $0089$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $89$.
