Solve 128/100

$$\frac { 128 } { 100 }$$

Evaluate

$$\frac{32}{25}=1.28$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 128

$$\begin{array}{l}\phantom{100)}\phantom{1}\\100\overline{)128}\\\end{array}$$

Since 1 is less than 100, use the next digit 2 from dividend 128 and add 0 to the quotient

$$\begin{array}{l}\phantom{100)}0\phantom{2}\\100\overline{)128}\\\end{array}$$

Use the 2^{nd} digit 2 from dividend 128

$$\begin{array}{l}\phantom{100)}0\phantom{3}\\100\overline{)128}\\\end{array}$$

Since 12 is less than 100, use the next digit 8 from dividend 128 and add 0 to the quotient

$$\begin{array}{l}\phantom{100)}00\phantom{4}\\100\overline{)128}\\\end{array}$$

Use the 3^{rd} digit 8 from dividend 128

$$\begin{array}{l}\phantom{100)}00\phantom{5}\\100\overline{)128}\\\end{array}$$

Find closest multiple of 100 to 128. We see that 1 \times 100 = 100 is the nearest. Now subtract 100 from 128 to get reminder 28. Add 1 to quotient.

$$\begin{array}{l}\phantom{100)}001\phantom{6}\\100\overline{)128}\\\phantom{100)}\underline{\phantom{}100\phantom{}}\\\phantom{100)9}28\\\end{array}$$

Since 28 is less than 100, stop the division. The reminder is 28. The topmost line 001 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 1.

$$\text{Quotient: }1 \text{Reminder: }28$$

Factor

$$\frac{2 ^ {5}}{5 ^ {2}} = 1\frac{7}{25} = 1.28$$
