$$100 \div 20$$

Evaluate

$5$

Steps For Long Division Method

Use the $1^{st}$ digit $1$ from dividend $100$

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)100}\\\end{array}$$

Since $1$ is less than $20$, use the next digit $0$ from dividend $100$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)100}\\\end{array}$$

Use the $2^{nd}$ digit $0$ from dividend $100$

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)100}\\\end{array}$$

Since $10$ is less than $20$, use the next digit $0$ from dividend $100$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{20)}00\phantom{4}\\20\overline{)100}\\\end{array}$$

Use the $3^{rd}$ digit $0$ from dividend $100$

$$\begin{array}{l}\phantom{20)}00\phantom{5}\\20\overline{)100}\\\end{array}$$

Find closest multiple of $20$ to $100$. We see that $5 \times 20 = 100$ is the nearest. Now subtract $100$ from $100$ to get reminder $0$. Add $5$ to quotient.

$$\begin{array}{l}\phantom{20)}005\phantom{6}\\20\overline{)100}\\\phantom{20)}\underline{\phantom{}100\phantom{}}\\\phantom{20)999}0\\\end{array}$$

Since $0$ is less than $20$, stop the division. The reminder is $0$. The topmost line $005$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $5$.

$$\text{Quotient: }5$$ $$\text{Reminder: }0$$
