Solve 640div400

$$640 \div 400$$

Evaluate

$$\frac{8}{5}=1.6$$

Steps For Long Division Method

Use the 1^{st} digit 6 from dividend 640

$$\begin{array}{l}\phantom{400)}\phantom{1}\\400\overline{)640}\\\end{array}$$

Since 6 is less than 400, use the next digit 4 from dividend 640 and add 0 to the quotient

$$\begin{array}{l}\phantom{400)}0\phantom{2}\\400\overline{)640}\\\end{array}$$

Use the 2^{nd} digit 4 from dividend 640

$$\begin{array}{l}\phantom{400)}0\phantom{3}\\400\overline{)640}\\\end{array}$$

Since 64 is less than 400, use the next digit 0 from dividend 640 and add 0 to the quotient

$$\begin{array}{l}\phantom{400)}00\phantom{4}\\400\overline{)640}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 640

$$\begin{array}{l}\phantom{400)}00\phantom{5}\\400\overline{)640}\\\end{array}$$

Find closest multiple of 400 to 640. We see that 1 \times 400 = 400 is the nearest. Now subtract 400 from 640 to get reminder 240. Add 1 to quotient.

$$\begin{array}{l}\phantom{400)}001\phantom{6}\\400\overline{)640}\\\phantom{400)}\underline{\phantom{}400\phantom{}}\\\phantom{400)}240\\\end{array}$$

Since 240 is less than 400, stop the division. The reminder is 240. The topmost line 001 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.

$$\text{Quotient: }1 \text{Reminder: }240$$

Factor

$$\frac{2 ^ {3}}{5} = 1\frac{3}{5} = 1.6$$
