Solve 1630div20

$$1630 \div 20$$

Evaluate

$$\frac{163}{2}=81.5$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 1630

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)1630}\\\end{array}$$

Since 1 is less than 20, use the next digit 6 from dividend 1630 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)1630}\\\end{array}$$

Use the 2^{nd} digit 6 from dividend 1630

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)1630}\\\end{array}$$

Since 16 is less than 20, use the next digit 3 from dividend 1630 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}00\phantom{4}\\20\overline{)1630}\\\end{array}$$

Use the 3^{rd} digit 3 from dividend 1630

$$\begin{array}{l}\phantom{20)}00\phantom{5}\\20\overline{)1630}\\\end{array}$$

Find closest multiple of 20 to 163. We see that 8 \times 20 = 160 is the nearest. Now subtract 160 from 163 to get reminder 3. Add 8 to quotient.

$$\begin{array}{l}\phantom{20)}008\phantom{6}\\20\overline{)1630}\\\phantom{20)}\underline{\phantom{}160\phantom{9}}\\\phantom{20)99}3\\\end{array}$$

Use the 4^{th} digit 0 from dividend 1630

$$\begin{array}{l}\phantom{20)}008\phantom{7}\\20\overline{)1630}\\\phantom{20)}\underline{\phantom{}160\phantom{9}}\\\phantom{20)99}30\\\end{array}$$

Find closest multiple of 20 to 30. We see that 1 \times 20 = 20 is the nearest. Now subtract 20 from 30 to get reminder 10. Add 1 to quotient.

$$\begin{array}{l}\phantom{20)}0081\phantom{8}\\20\overline{)1630}\\\phantom{20)}\underline{\phantom{}160\phantom{9}}\\\phantom{20)99}30\\\phantom{20)}\underline{\phantom{99}20\phantom{}}\\\phantom{20)99}10\\\end{array}$$

Since 10 is less than 20, stop the division. The reminder is 10. The topmost line 0081 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 81.

$$\text{Quotient: }81 \text{Reminder: }10$$

Factor

$$\frac{163}{2} = 81\frac{1}{2} = 81.5$$
