Solve 640:128

$$640 : 128$$

Evaluate

$$5$$

Steps For Long Division Method

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

$$\begin{array}{l}\phantom{128)}\phantom{1}\\128\overline{)640}\\\end{array}$$

Since 6 is less than 128, use the next digit 4 from dividend 640 and add 0 to the quotient

$$\begin{array}{l}\phantom{128)}0\phantom{2}\\128\overline{)640}\\\end{array}$$

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

$$\begin{array}{l}\phantom{128)}0\phantom{3}\\128\overline{)640}\\\end{array}$$

Since 64 is less than 128, use the next digit 0 from dividend 640 and add 0 to the quotient

$$\begin{array}{l}\phantom{128)}00\phantom{4}\\128\overline{)640}\\\end{array}$$

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

$$\begin{array}{l}\phantom{128)}00\phantom{5}\\128\overline{)640}\\\end{array}$$

Find closest multiple of 128 to 640. We see that 5 \times 128 = 640 is the nearest. Now subtract 640 from 640 to get reminder 0. Add 5 to quotient.

$$\begin{array}{l}\phantom{128)}005\phantom{6}\\128\overline{)640}\\\phantom{128)}\underline{\phantom{}640\phantom{}}\\\phantom{128)999}0\\\end{array}$$

Since 0 is less than 128, stop the division. The reminder is 0. The topmost line 005 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 5.

$$\text{Quotient: }5 \text{Reminder: }0$$

Factor

$$5$$
