Solve 39:20

$$39 : 20$$

Evaluate

$$\frac{39}{20}=1.95$$

Steps For Long Division Method

Use the 1^{st} digit 3 from dividend 39

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)39}\\\end{array}$$

Since 3 is less than 20, use the next digit 9 from dividend 39 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)39}\\\end{array}$$

Use the 2^{nd} digit 9 from dividend 39

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)39}\\\end{array}$$

Find closest multiple of 20 to 39. We see that 1 \times 20 = 20 is the nearest. Now subtract 20 from 39 to get reminder 19. Add 1 to quotient.

$$\begin{array}{l}\phantom{20)}01\phantom{4}\\20\overline{)39}\\\phantom{20)}\underline{\phantom{}20\phantom{}}\\\phantom{20)}19\\\end{array}$$

Since 19 is less than 20, stop the division. The reminder is 19. The topmost line 01 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.

$$\text{Quotient: }1 \text{Reminder: }19$$

Factor

$$\frac{3 \cdot 13}{2 ^ {2} \cdot 5} = 1\frac{19}{20} = 1.95$$
