Solve 630div20

$$630 \div 20$$

Evaluate

$$\frac{63}{2}=31.5$$

Steps For Long Division Method

Use the 1^{st} digit 6 from dividend 630

$$\begin{array}{l}\phantom{20)}\phantom{1}\\20\overline{)630}\\\end{array}$$

Since 6 is less than 20, use the next digit 3 from dividend 630 and add 0 to the quotient

$$\begin{array}{l}\phantom{20)}0\phantom{2}\\20\overline{)630}\\\end{array}$$

Use the 2^{nd} digit 3 from dividend 630

$$\begin{array}{l}\phantom{20)}0\phantom{3}\\20\overline{)630}\\\end{array}$$

Find closest multiple of 20 to 63. We see that 3 \times 20 = 60 is the nearest. Now subtract 60 from 63 to get reminder 3. Add 3 to quotient.

$$\begin{array}{l}\phantom{20)}03\phantom{4}\\20\overline{)630}\\\phantom{20)}\underline{\phantom{}60\phantom{9}}\\\phantom{20)9}3\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 630

$$\begin{array}{l}\phantom{20)}03\phantom{5}\\20\overline{)630}\\\phantom{20)}\underline{\phantom{}60\phantom{9}}\\\phantom{20)9}30\\\end{array}$$

Find closest multiple of 20 to 30. We see that 1 \times 20 = 20 is the nearest. Now subtract 20 from 30 to get reminder 10. Add 1 to quotient.

$$\begin{array}{l}\phantom{20)}031\phantom{6}\\20\overline{)630}\\\phantom{20)}\underline{\phantom{}60\phantom{9}}\\\phantom{20)9}30\\\phantom{20)}\underline{\phantom{9}20\phantom{}}\\\phantom{20)9}10\\\end{array}$$

Since 10 is less than 20, stop the division. The reminder is 10. The topmost line 031 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 31.

$$\text{Quotient: }31 \text{Reminder: }10$$

Factor

$$\frac{3 ^ {2} \cdot 7}{2} = 31\frac{1}{2} = 31.5$$
