Solve 216div18

$$216 \div 18$$

Evaluate

$$12$$

Steps For Long Division Method

Use the 1^{st} digit 2 from dividend 216

$$\begin{array}{l}\phantom{18)}\phantom{1}\\18\overline{)216}\\\end{array}$$

Since 2 is less than 18, use the next digit 1 from dividend 216 and add 0 to the quotient

$$\begin{array}{l}\phantom{18)}0\phantom{2}\\18\overline{)216}\\\end{array}$$

Use the 2^{nd} digit 1 from dividend 216

$$\begin{array}{l}\phantom{18)}0\phantom{3}\\18\overline{)216}\\\end{array}$$

Find closest multiple of 18 to 21. We see that 1 \times 18 = 18 is the nearest. Now subtract 18 from 21 to get reminder 3. Add 1 to quotient.

$$\begin{array}{l}\phantom{18)}01\phantom{4}\\18\overline{)216}\\\phantom{18)}\underline{\phantom{}18\phantom{9}}\\\phantom{18)9}3\\\end{array}$$

Use the 3^{rd} digit 6 from dividend 216

$$\begin{array}{l}\phantom{18)}01\phantom{5}\\18\overline{)216}\\\phantom{18)}\underline{\phantom{}18\phantom{9}}\\\phantom{18)9}36\\\end{array}$$

Find closest multiple of 18 to 36. We see that 2 \times 18 = 36 is the nearest. Now subtract 36 from 36 to get reminder 0. Add 2 to quotient.

$$\begin{array}{l}\phantom{18)}012\phantom{6}\\18\overline{)216}\\\phantom{18)}\underline{\phantom{}18\phantom{9}}\\\phantom{18)9}36\\\phantom{18)}\underline{\phantom{9}36\phantom{}}\\\phantom{18)999}0\\\end{array}$$

Since 0 is less than 18, stop the division. The reminder is 0. The topmost line 012 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 12.

$$\text{Quotient: }12 \text{Reminder: }0$$

Factor

$$2^{2}\times 3$$
