$$19781 \div 258 =$$

Evaluate

$$\frac{19781}{258}\approx 76.670542636$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 19781

$$\begin{array}{l}\phantom{258)}\phantom{1}\\258\overline{)19781}\\\end{array}$$

Since 1 is less than 258, use the next digit 9 from dividend 19781 and add 0 to the quotient

$$\begin{array}{l}\phantom{258)}0\phantom{2}\\258\overline{)19781}\\\end{array}$$

Use the 2^{nd} digit 9 from dividend 19781

$$\begin{array}{l}\phantom{258)}0\phantom{3}\\258\overline{)19781}\\\end{array}$$

Since 19 is less than 258, use the next digit 7 from dividend 19781 and add 0 to the quotient

$$\begin{array}{l}\phantom{258)}00\phantom{4}\\258\overline{)19781}\\\end{array}$$

Use the 3^{rd} digit 7 from dividend 19781

$$\begin{array}{l}\phantom{258)}00\phantom{5}\\258\overline{)19781}\\\end{array}$$

Since 197 is less than 258, use the next digit 8 from dividend 19781 and add 0 to the quotient

$$\begin{array}{l}\phantom{258)}000\phantom{6}\\258\overline{)19781}\\\end{array}$$

Use the 4^{th} digit 8 from dividend 19781

$$\begin{array}{l}\phantom{258)}000\phantom{7}\\258\overline{)19781}\\\end{array}$$

Find closest multiple of 258 to 1978. We see that 7 \times 258 = 1806 is the nearest. Now subtract 1806 from 1978 to get reminder 172. Add 7 to quotient.

$$\begin{array}{l}\phantom{258)}0007\phantom{8}\\258\overline{)19781}\\\phantom{258)}\underline{\phantom{}1806\phantom{9}}\\\phantom{258)9}172\\\end{array}$$

Use the 5^{th} digit 1 from dividend 19781

$$\begin{array}{l}\phantom{258)}0007\phantom{9}\\258\overline{)19781}\\\phantom{258)}\underline{\phantom{}1806\phantom{9}}\\\phantom{258)9}1721\\\end{array}$$

Find closest multiple of 258 to 1721. We see that 6 \times 258 = 1548 is the nearest. Now subtract 1548 from 1721 to get reminder 173. Add 6 to quotient.

$$\begin{array}{l}\phantom{258)}00076\phantom{10}\\258\overline{)19781}\\\phantom{258)}\underline{\phantom{}1806\phantom{9}}\\\phantom{258)9}1721\\\phantom{258)}\underline{\phantom{9}1548\phantom{}}\\\phantom{258)99}173\\\end{array}$$

Since 173 is less than 258, stop the division. The reminder is 173. The topmost line 00076 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 76.

$$\text{Quotient: }76 \text{Reminder: }173$$

Factor

$$\frac{131 \cdot 151}{2 \cdot 3 \cdot 43} = 76\frac{173}{258} = 76.67054263565892$$
