Question

$$20\div13$$

Evaluate

$\frac{20}{13}\approx 1.538461538$

Steps For Long Division Method

Use the $1^{st}$ digit $2$ from dividend $20$

$$\begin{array}{l}\phantom{13)}\phantom{1}\\13\overline{)20}\\\end{array}$$

Since $2$ is less than $13$, use the next digit $0$ from dividend $20$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{13)}0\phantom{2}\\13\overline{)20}\\\end{array}$$

Use the $2^{nd}$ digit $0$ from dividend $20$

$$\begin{array}{l}\phantom{13)}0\phantom{3}\\13\overline{)20}\\\end{array}$$

Find closest multiple of $13$ to $20$. We see that $1 \times 13 = 13$ is the nearest. Now subtract $13$ from $20$ to get reminder $7$. Add $1$ to quotient.

$$\begin{array}{l}\phantom{13)}01\phantom{4}\\13\overline{)20}\\\phantom{13)}\underline{\phantom{}13\phantom{}}\\\phantom{13)9}7\\\end{array}$$

Since $7$ is less than $13$, stop the division. The reminder is $7$. The topmost line $01$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $1$.

$$\text{Quotient: }1$$ $$\text{Reminder: }7$$
