Solve 162div20

$$162 \div 20$$

Evaluate

$$\frac{81}{10}=8.1$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 162

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)162}\\\end{array}$$

Since 1 is less than 20, use the next digit 6 from dividend 162 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)162}\\\end{array}$$

Use the 2^{nd} digit 6 from dividend 162

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)162}\\\end{array}$$

Since 16 is less than 20, use the next digit 2 from dividend 162 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}00\phantom{4}\\20\overline{)162}\\\end{array}$$

Use the 3^{rd} digit 2 from dividend 162

$$\begin{array}{l}\phantom{20)}00\phantom{5}\\20\overline{)162}\\\end{array}$$

Find closest multiple of 20 to 162. We see that 8 \times 20 = 160 is the nearest. Now subtract 160 from 162 to get reminder 2. Add 8 to quotient.

$$\begin{array}{l}\phantom{20)}008\phantom{6}\\20\overline{)162}\\\phantom{20)}\underline{\phantom{}160\phantom{}}\\\phantom{20)99}2\\\end{array}$$

Since 2 is less than 20, stop the division. The reminder is 2. The topmost line 008 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 8.

$$\text{Quotient: }8 \text{Reminder: }2$$

Factor

$$\frac{3 ^ {4}}{2 \cdot 5} = 8\frac{1}{10} = 8.1$$
