Solve 144div21

$$144 \div 21$$

Evaluate

$$\frac{48}{7}\approx 6.857142857$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 144

$$\begin{array}{l}\phantom{21)}\phantom{1}\\21\overline{)144}\\\end{array}$$

Since 1 is less than 21, use the next digit 4 from dividend 144 and add 0 to the quotient

$$\begin{array}{l}\phantom{21)}0\phantom{2}\\21\overline{)144}\\\end{array}$$

Use the 2^{nd} digit 4 from dividend 144

$$\begin{array}{l}\phantom{21)}0\phantom{3}\\21\overline{)144}\\\end{array}$$

Since 14 is less than 21, use the next digit 4 from dividend 144 and add 0 to the quotient

$$\begin{array}{l}\phantom{21)}00\phantom{4}\\21\overline{)144}\\\end{array}$$

Use the 3^{rd} digit 4 from dividend 144

$$\begin{array}{l}\phantom{21)}00\phantom{5}\\21\overline{)144}\\\end{array}$$

Find closest multiple of 21 to 144. We see that 6 \times 21 = 126 is the nearest. Now subtract 126 from 144 to get reminder 18. Add 6 to quotient.

$$\begin{array}{l}\phantom{21)}006\phantom{6}\\21\overline{)144}\\\phantom{21)}\underline{\phantom{}126\phantom{}}\\\phantom{21)9}18\\\end{array}$$

Since 18 is less than 21, stop the division. The reminder is 18. The topmost line 006 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 6.

$$\text{Quotient: }6 \text{Reminder: }18$$

Factor

$$\frac{2 ^ {4} \cdot 3}{7} = 6\frac{6}{7} = 6.857142857142857$$
