Solve 310div12

$$310 \div 12$$

Evaluate

$$\frac{155}{6}\approx 25.833333333$$

Steps For Long Division Method

Use the 1^{st} digit 3 from dividend 310

$$\begin{array}{l}\phantom{12)}\phantom{1}\\12\overline{)310}\\\end{array}$$

Since 3 is less than 12, use the next digit 1 from dividend 310 and add 0 to the quotient

$$\begin{array}{l}\phantom{12)}0\phantom{2}\\12\overline{)310}\\\end{array}$$

Use the 2^{nd} digit 1 from dividend 310

$$\begin{array}{l}\phantom{12)}0\phantom{3}\\12\overline{)310}\\\end{array}$$

Find closest multiple of 12 to 31. We see that 2 \times 12 = 24 is the nearest. Now subtract 24 from 31 to get reminder 7. Add 2 to quotient.

$$\begin{array}{l}\phantom{12)}02\phantom{4}\\12\overline{)310}\\\phantom{12)}\underline{\phantom{}24\phantom{9}}\\\phantom{12)9}7\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 310

$$\begin{array}{l}\phantom{12)}02\phantom{5}\\12\overline{)310}\\\phantom{12)}\underline{\phantom{}24\phantom{9}}\\\phantom{12)9}70\\\end{array}$$

Find closest multiple of 12 to 70. We see that 5 \times 12 = 60 is the nearest. Now subtract 60 from 70 to get reminder 10. Add 5 to quotient.

$$\begin{array}{l}\phantom{12)}025\phantom{6}\\12\overline{)310}\\\phantom{12)}\underline{\phantom{}24\phantom{9}}\\\phantom{12)9}70\\\phantom{12)}\underline{\phantom{9}60\phantom{}}\\\phantom{12)9}10\\\end{array}$$

Since 10 is less than 12, stop the division. The reminder is 10. The topmost line 025 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 25.

$$\text{Quotient: }25 \text{Reminder: }10$$

Factor

$$\frac{5 \cdot 31}{2 \cdot 3} = 25\frac{5}{6} = 25.833333333333332$$
