Steps For Long Division Method

Use the $1^{st}$ digit $4$ from dividend $480$

$$\begin{array}{l}\phantom{480)}\phantom{1}\\480\overline{)480}\\\end{array}$$

Since $4$ is less than $480$, use the next digit $8$ from dividend $480$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{480)}0\phantom{2}\\480\overline{)480}\\\end{array}$$

Use the $2^{nd}$ digit $8$ from dividend $480$

$$\begin{array}{l}\phantom{480)}0\phantom{3}\\480\overline{)480}\\\end{array}$$

Since $48$ is less than $480$, use the next digit $0$ from dividend $480$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{480)}00\phantom{4}\\480\overline{)480}\\\end{array}$$

Use the $3^{rd}$ digit $0$ from dividend $480$

$$\begin{array}{l}\phantom{480)}00\phantom{5}\\480\overline{)480}\\\end{array}$$

Find closest multiple of $480$ to $480$. We see that $1 \times 480 = 480$ is the nearest. Now subtract $480$ from $480$ to get reminder $0$. Add $1$ to quotient.

$$\begin{array}{l}\phantom{480)}001\phantom{6}\\480\overline{)480}\\\phantom{480)}\underline{\phantom{}480\phantom{}}\\\phantom{480)999}0\\\end{array}$$

Since $0$ is less than $480$, stop the division. The reminder is $0$. The topmost line $001$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $1$.

$$\text{Quotient: }1$$ $$\text{Reminder: }0$$
