Solve 123div30

$$123 \div 30$$

Evaluate

$$\frac{41}{10}=4.1$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 123

$$\begin{array}{l}\phantom{30)}\phantom{1}\\30\overline{)123}\\\end{array}$$

Since 1 is less than 30, use the next digit 2 from dividend 123 and add 0 to the quotient

$$\begin{array}{l}\phantom{30)}0\phantom{2}\\30\overline{)123}\\\end{array}$$

Use the 2^{nd} digit 2 from dividend 123

$$\begin{array}{l}\phantom{30)}0\phantom{3}\\30\overline{)123}\\\end{array}$$

Since 12 is less than 30, use the next digit 3 from dividend 123 and add 0 to the quotient

$$\begin{array}{l}\phantom{30)}00\phantom{4}\\30\overline{)123}\\\end{array}$$

Use the 3^{rd} digit 3 from dividend 123

$$\begin{array}{l}\phantom{30)}00\phantom{5}\\30\overline{)123}\\\end{array}$$

Find closest multiple of 30 to 123. We see that 4 \times 30 = 120 is the nearest. Now subtract 120 from 123 to get reminder 3. Add 4 to quotient.

$$\begin{array}{l}\phantom{30)}004\phantom{6}\\30\overline{)123}\\\phantom{30)}\underline{\phantom{}120\phantom{}}\\\phantom{30)99}3\\\end{array}$$

Since 3 is less than 30, stop the division. The reminder is 3. The topmost line 004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.

$$\text{Quotient: }4 \text{Reminder: }3$$

Factor

$$\frac{41}{2 \cdot 5} = 4\frac{1}{10} = 4.1$$
