Find closest multiple of $30$ to $77$. We see that $2 \times 30 = 60$ is the nearest. Now subtract $60$ from $77$ to get reminder $17$. Add $2$ to quotient.
Find closest multiple of $30$ to $179$. We see that $5 \times 30 = 150$ is the nearest. Now subtract $150$ from $179$ to get reminder $29$. Add $5$ to quotient.
Since $29$ is less than $30$, stop the division. The reminder is $29$. The topmost line $025$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $25$.
