Solve 321/20

$$\frac { 321 } { 20 }$$

Evaluate

$$\frac{321}{20}=16.05$$

Steps For Long Division Method

Use the 1^{st} digit 3 from dividend 321

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)321}\\\end{array}$$

Since 3 is less than 20, use the next digit 2 from dividend 321 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)321}\\\end{array}$$

Use the 2^{nd} digit 2 from dividend 321

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)321}\\\end{array}$$

Find closest multiple of 20 to 32. We see that 1 \times 20 = 20 is the nearest. Now subtract 20 from 32 to get reminder 12. Add 1 to quotient.

$$\begin{array}{l}\phantom{20)}01\phantom{4}\\20\overline{)321}\\\phantom{20)}\underline{\phantom{}20\phantom{9}}\\\phantom{20)}12\\\end{array}$$

Use the 3^{rd} digit 1 from dividend 321

$$\begin{array}{l}\phantom{20)}01\phantom{5}\\20\overline{)321}\\\phantom{20)}\underline{\phantom{}20\phantom{9}}\\\phantom{20)}121\\\end{array}$$

Find closest multiple of 20 to 121. We see that 6 \times 20 = 120 is the nearest. Now subtract 120 from 121 to get reminder 1. Add 6 to quotient.

$$\begin{array}{l}\phantom{20)}016\phantom{6}\\20\overline{)321}\\\phantom{20)}\underline{\phantom{}20\phantom{9}}\\\phantom{20)}121\\\phantom{20)}\underline{\phantom{}120\phantom{}}\\\phantom{20)99}1\\\end{array}$$

Since 1 is less than 20, stop the division. The reminder is 1. The topmost line 016 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 16.

$$\text{Quotient: }16 \text{Reminder: }1$$

Factor

$$\frac{3 \cdot 107}{2 ^ {2} \cdot 5} = 16\frac{1}{20} = 16.05$$
