Solve 100div31

$$100 \div 31$$

Evaluate

$$\frac{100}{31}\approx 3.225806452$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 100

$$\begin{array}{l}\phantom{31)}\phantom{1}\\31\overline{)100}\\\end{array}$$

Since 1 is less than 31, use the next digit 0 from dividend 100 and add 0 to the quotient

$$\begin{array}{l}\phantom{31)}0\phantom{2}\\31\overline{)100}\\\end{array}$$

Use the 2^{nd} digit 0 from dividend 100

$$\begin{array}{l}\phantom{31)}0\phantom{3}\\31\overline{)100}\\\end{array}$$

Since 10 is less than 31, use the next digit 0 from dividend 100 and add 0 to the quotient

$$\begin{array}{l}\phantom{31)}00\phantom{4}\\31\overline{)100}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 100

$$\begin{array}{l}\phantom{31)}00\phantom{5}\\31\overline{)100}\\\end{array}$$

Find closest multiple of 31 to 100. We see that 3 \times 31 = 93 is the nearest. Now subtract 93 from 100 to get reminder 7. Add 3 to quotient.

$$\begin{array}{l}\phantom{31)}003\phantom{6}\\31\overline{)100}\\\phantom{31)}\underline{\phantom{9}93\phantom{}}\\\phantom{31)99}7\\\end{array}$$

Since 7 is less than 31, stop the division. The reminder is 7. The topmost line 003 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 3.

$$\text{Quotient: }3 \text{Reminder: }7$$

Factor

$$\frac{2 ^ {2} \cdot 5 ^ {2}}{31} = 3\frac{7}{31} = 3.225806451612903$$
