Solve 210/40

$$\frac { 210 } { 40 }$$

Evaluate

$$\frac{21}{4}=5.25$$

Steps For Long Division Method

Use the 1^{st} digit 2 from dividend 210

$$\begin{array}{l}\phantom{40)}\phantom{1}\\40\overline{)210}\\\end{array}$$

Since 2 is less than 40, use the next digit 1 from dividend 210 and add 0 to the quotient

$$\begin{array}{l}\phantom{40)}0\phantom{2}\\40\overline{)210}\\\end{array}$$

Use the 2^{nd} digit 1 from dividend 210

$$\begin{array}{l}\phantom{40)}0\phantom{3}\\40\overline{)210}\\\end{array}$$

Since 21 is less than 40, use the next digit 0 from dividend 210 and add 0 to the quotient

$$\begin{array}{l}\phantom{40)}00\phantom{4}\\40\overline{)210}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 210

$$\begin{array}{l}\phantom{40)}00\phantom{5}\\40\overline{)210}\\\end{array}$$

Find closest multiple of 40 to 210. We see that 5 \times 40 = 200 is the nearest. Now subtract 200 from 210 to get reminder 10. Add 5 to quotient.

$$\begin{array}{l}\phantom{40)}005\phantom{6}\\40\overline{)210}\\\phantom{40)}\underline{\phantom{}200\phantom{}}\\\phantom{40)9}10\\\end{array}$$

Since 10 is less than 40, stop the division. The reminder is 10. The topmost line 005 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 5.

$$\text{Quotient: }5 \text{Reminder: }10$$

Factor

$$\frac{3 \cdot 7}{2 ^ {2}} = 5\frac{1}{4} = 5.25$$
