Solve 64:15

$$64 : 15$$

Evaluate

$$\frac{64}{15}\approx 4.266666667$$

Steps For Long Division Method

Use the 1^{st} digit 6 from dividend 64

$$\begin{array}{l}\phantom{15)}\phantom{1}\\15\overline{)64}\\\end{array}$$

Since 6 is less than 15, use the next digit 4 from dividend 64 and add 0 to the quotient

$$\begin{array}{l}\phantom{15)}0\phantom{2}\\15\overline{)64}\\\end{array}$$

Use the 2^{nd} digit 4 from dividend 64

$$\begin{array}{l}\phantom{15)}0\phantom{3}\\15\overline{)64}\\\end{array}$$

Find closest multiple of 15 to 64. We see that 4 \times 15 = 60 is the nearest. Now subtract 60 from 64 to get reminder 4. Add 4 to quotient.

$$\begin{array}{l}\phantom{15)}04\phantom{4}\\15\overline{)64}\\\phantom{15)}\underline{\phantom{}60\phantom{}}\\\phantom{15)9}4\\\end{array}$$

Since 4 is less than 15, stop the division. The reminder is 4. The topmost line 04 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.

$$\text{Quotient: }4 \text{Reminder: }4$$

Factor

$$\frac{2 ^ {6}}{3 \cdot 5} = 4\frac{4}{15} = 4.266666666666667$$
