Solve 780div25

$$780 \div 25$$

Evaluate

$$\frac{156}{5}=31.2$$

Steps For Long Division Method

Use the 1^{st} digit 7 from dividend 780

$$\begin{array}{l}\phantom{25)}\phantom{1}\\25\overline{)780}\\\end{array}$$

Since 7 is less than 25, use the next digit 8 from dividend 780 and add 0 to the quotient

$$\begin{array}{l}\phantom{25)}0\phantom{2}\\25\overline{)780}\\\end{array}$$

Use the 2^{nd} digit 8 from dividend 780

$$\begin{array}{l}\phantom{25)}0\phantom{3}\\25\overline{)780}\\\end{array}$$

Find closest multiple of 25 to 78. We see that 3 \times 25 = 75 is the nearest. Now subtract 75 from 78 to get reminder 3. Add 3 to quotient.

$$\begin{array}{l}\phantom{25)}03\phantom{4}\\25\overline{)780}\\\phantom{25)}\underline{\phantom{}75\phantom{9}}\\\phantom{25)9}3\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 780

$$\begin{array}{l}\phantom{25)}03\phantom{5}\\25\overline{)780}\\\phantom{25)}\underline{\phantom{}75\phantom{9}}\\\phantom{25)9}30\\\end{array}$$

Find closest multiple of 25 to 30. We see that 1 \times 25 = 25 is the nearest. Now subtract 25 from 30 to get reminder 5. Add 1 to quotient.

$$\begin{array}{l}\phantom{25)}031\phantom{6}\\25\overline{)780}\\\phantom{25)}\underline{\phantom{}75\phantom{9}}\\\phantom{25)9}30\\\phantom{25)}\underline{\phantom{9}25\phantom{}}\\\phantom{25)99}5\\\end{array}$$

Since 5 is less than 25, stop the division. The reminder is 5. The topmost line 031 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 31.

$$\text{Quotient: }31 \text{Reminder: }5$$

Factor

$$\frac{2 ^ {2} \cdot 3 \cdot 13}{5} = 31\frac{1}{5} = 31.2$$
