Find closest multiple of $20$ to $62$. We see that $3 \times 20 = 60$ is the nearest. Now subtract $60$ from $62$ to get reminder $2$. Add $3$ to quotient.
Find closest multiple of $20$ to $25$. We see that $1 \times 20 = 20$ is the nearest. Now subtract $20$ from $25$ to get reminder $5$. Add $1$ to quotient.
Since $5$ is less than $20$, stop the division. The reminder is $5$. The topmost line $031$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $31$.
