Solve 1000div80=

$$1000 \div 80=$$

Evaluate

$$\frac{25}{2}=12.5$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 1000

$$\begin{array}{l}\phantom{80)}\phantom{1}\\80\overline{)1000}\\\end{array}$$

Since 1 is less than 80, use the next digit 0 from dividend 1000 and add 0 to the quotient

$$\begin{array}{l}\phantom{80)}0\phantom{2}\\80\overline{)1000}\\\end{array}$$

Use the 2^{nd} digit 0 from dividend 1000

$$\begin{array}{l}\phantom{80)}0\phantom{3}\\80\overline{)1000}\\\end{array}$$

Since 10 is less than 80, use the next digit 0 from dividend 1000 and add 0 to the quotient

$$\begin{array}{l}\phantom{80)}00\phantom{4}\\80\overline{)1000}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 1000

$$\begin{array}{l}\phantom{80)}00\phantom{5}\\80\overline{)1000}\\\end{array}$$

Find closest multiple of 80 to 100. We see that 1 \times 80 = 80 is the nearest. Now subtract 80 from 100 to get reminder 20. Add 1 to quotient.

$$\begin{array}{l}\phantom{80)}001\phantom{6}\\80\overline{)1000}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}20\\\end{array}$$

Use the 4^{th} digit 0 from dividend 1000

$$\begin{array}{l}\phantom{80)}001\phantom{7}\\80\overline{)1000}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}200\\\end{array}$$

Find closest multiple of 80 to 200. We see that 2 \times 80 = 160 is the nearest. Now subtract 160 from 200 to get reminder 40. Add 2 to quotient.

$$\begin{array}{l}\phantom{80)}0012\phantom{8}\\80\overline{)1000}\\\phantom{80)}\underline{\phantom{9}80\phantom{9}}\\\phantom{80)9}200\\\phantom{80)}\underline{\phantom{9}160\phantom{}}\\\phantom{80)99}40\\\end{array}$$

Since 40 is less than 80, stop the division. The reminder is 40. The topmost line 0012 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 12.

$$\text{Quotient: }12 \text{Reminder: }40$$

Factor

$$\frac{5 ^ {2}}{2} = 12\frac{1}{2} = 12.5$$
