Solve 70div20=

$$70 \div 20 =$$

Evaluate

$$\frac{7}{2}=3.5$$

Steps For Long Division Method

Use the 1^{st} digit 7 from dividend 70

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)70}\\\end{array}$$

Since 7 is less than 20, use the next digit 0 from dividend 70 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)70}\\\end{array}$$

Use the 2^{nd} digit 0 from dividend 70

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)70}\\\end{array}$$

Find closest multiple of 20 to 70. We see that 3 \times 20 = 60 is the nearest. Now subtract 60 from 70 to get reminder 10. Add 3 to quotient.

$$\begin{array}{l}\phantom{20)}03\phantom{4}\\20\overline{)70}\\\phantom{20)}\underline{\phantom{}60\phantom{}}\\\phantom{20)}10\\\end{array}$$

Since 10 is less than 20, stop the division. The reminder is 10. The topmost line 03 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3.

$$\text{Quotient: }3 \text{Reminder: }10$$

Factor

$$\frac{7}{2} = 3\frac{1}{2} = 3.5$$
