Question

$$168/21$$

Evaluate

$8$

Steps For Long Division Method

Use the $1^{st}$ digit $1$ from dividend $168$

$$\begin{array}{l}\phantom{21)}\phantom{1}\\21\overline{)168}\\\end{array}$$

Since $1$ is less than $21$, use the next digit $6$ from dividend $168$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{21)}0\phantom{2}\\21\overline{)168}\\\end{array}$$

Use the $2^{nd}$ digit $6$ from dividend $168$

$$\begin{array}{l}\phantom{21)}0\phantom{3}\\21\overline{)168}\\\end{array}$$

Since $16$ is less than $21$, use the next digit $8$ from dividend $168$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{21)}00\phantom{4}\\21\overline{)168}\\\end{array}$$

Use the $3^{rd}$ digit $8$ from dividend $168$

$$\begin{array}{l}\phantom{21)}00\phantom{5}\\21\overline{)168}\\\end{array}$$

Find closest multiple of $21$ to $168$. We see that $8 \times 21 = 168$ is the nearest. Now subtract $168$ from $168$ to get reminder $0$. Add $8$ to quotient.

$$\begin{array}{l}\phantom{21)}008\phantom{6}\\21\overline{)168}\\\phantom{21)}\underline{\phantom{}168\phantom{}}\\\phantom{21)999}0\\\end{array}$$

Since $0$ is less than $21$, stop the division. The reminder is $0$. The topmost line $008$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $8$.

$$\text{Quotient: }8$$ $$\text{Reminder: }0$$
