Solve 85:39=

$$85 : 39 =$$

Evaluate

$$\frac{85}{39}\approx 2.179487179$$

Steps For Long Division Method

Use the 1^{st} digit 8 from dividend 85

$$\begin{array}{l}\phantom{39)}\phantom{1}\\39\overline{)85}\\\end{array}$$

Since 8 is less than 39, use the next digit 5 from dividend 85 and add 0 to the quotient

$$\begin{array}{l}\phantom{39)}0\phantom{2}\\39\overline{)85}\\\end{array}$$

Use the 2^{nd} digit 5 from dividend 85

$$\begin{array}{l}\phantom{39)}0\phantom{3}\\39\overline{)85}\\\end{array}$$

Find closest multiple of 39 to 85. We see that 2 \times 39 = 78 is the nearest. Now subtract 78 from 85 to get reminder 7. Add 2 to quotient.

$$\begin{array}{l}\phantom{39)}02\phantom{4}\\39\overline{)85}\\\phantom{39)}\underline{\phantom{}78\phantom{}}\\\phantom{39)9}7\\\end{array}$$

Since 7 is less than 39, stop the division. The reminder is 7. The topmost line 02 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.

$$\text{Quotient: }2 \text{Reminder: }7$$

Factor

$$\frac{5 \cdot 17}{3 \cdot 13} = 2\frac{7}{39} = 2.1794871794871793$$
