Question

$$160/78$$

Evaluate

$\frac{80}{39}\approx 2.051282051$

Steps For Long Division Method

Use the $1^{st}$ digit $1$ from dividend $160$

$$\begin{array}{l}\phantom{78)}\phantom{1}\\78\overline{)160}\\\end{array}$$

Since $1$ is less than $78$, use the next digit $6$ from dividend $160$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{78)}0\phantom{2}\\78\overline{)160}\\\end{array}$$

Use the $2^{nd}$ digit $6$ from dividend $160$

$$\begin{array}{l}\phantom{78)}0\phantom{3}\\78\overline{)160}\\\end{array}$$

Since $16$ is less than $78$, use the next digit $0$ from dividend $160$ and add $0$ to the quotient

$$\begin{array}{l}\phantom{78)}00\phantom{4}\\78\overline{)160}\\\end{array}$$

Use the $3^{rd}$ digit $0$ from dividend $160$

$$\begin{array}{l}\phantom{78)}00\phantom{5}\\78\overline{)160}\\\end{array}$$

Find closest multiple of $78$ to $160$. We see that $2 \times 78 = 156$ is the nearest. Now subtract $156$ from $160$ to get reminder $4$. Add $2$ to quotient.

$$\begin{array}{l}\phantom{78)}002\phantom{6}\\78\overline{)160}\\\phantom{78)}\underline{\phantom{}156\phantom{}}\\\phantom{78)99}4\\\end{array}$$

Since $4$ is less than $78$, stop the division. The reminder is $4$. The topmost line $002$ is the quotient. Remove all zeros at the start of the quotient to get the actual quotient $2$.

$$\text{Quotient: }2$$ $$\text{Reminder: }4$$
