Solve 1800div400

$$1800 \div 400$$

Evaluate

$$\frac{9}{2}=4.5$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 1800

$$\begin{array}{l}\phantom{400)}\phantom{1}\\400\overline{)1800}\\\end{array}$$

Since 1 is less than 400, use the next digit 8 from dividend 1800 and add 0 to the quotient

$$\begin{array}{l}\phantom{400)}0\phantom{2}\\400\overline{)1800}\\\end{array}$$

Use the 2^{nd} digit 8 from dividend 1800

$$\begin{array}{l}\phantom{400)}0\phantom{3}\\400\overline{)1800}\\\end{array}$$

Since 18 is less than 400, use the next digit 0 from dividend 1800 and add 0 to the quotient

$$\begin{array}{l}\phantom{400)}00\phantom{4}\\400\overline{)1800}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 1800

$$\begin{array}{l}\phantom{400)}00\phantom{5}\\400\overline{)1800}\\\end{array}$$

Since 180 is less than 400, use the next digit 0 from dividend 1800 and add 0 to the quotient

$$\begin{array}{l}\phantom{400)}000\phantom{6}\\400\overline{)1800}\\\end{array}$$

Use the 4^{th} digit 0 from dividend 1800

$$\begin{array}{l}\phantom{400)}000\phantom{7}\\400\overline{)1800}\\\end{array}$$

Find closest multiple of 400 to 1800. We see that 4 \times 400 = 1600 is the nearest. Now subtract 1600 from 1800 to get reminder 200. Add 4 to quotient.

$$\begin{array}{l}\phantom{400)}0004\phantom{8}\\400\overline{)1800}\\\phantom{400)}\underline{\phantom{}1600\phantom{}}\\\phantom{400)9}200\\\end{array}$$

Since 200 is less than 400, stop the division. The reminder is 200. The topmost line 0004 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 4.

$$\text{Quotient: }4 \text{Reminder: }200$$

Factor

$$\frac{3 ^ {2}}{2} = 4\frac{1}{2} = 4.5$$
