Steps For Long Division Method

Use the 1^{st} digit 5 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}\phantom{1}\\7979\overline{)51000000}\\\end{array}$$

Since 5 is less than 7979, use the next digit 1 from dividend 51000000 and add 0 to the quotient

$$\begin{array}{l}\phantom{7979)}0\phantom{2}\\7979\overline{)51000000}\\\end{array}$$

Use the 2^{nd} digit 1 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}0\phantom{3}\\7979\overline{)51000000}\\\end{array}$$

Since 51 is less than 7979, use the next digit 0 from dividend 51000000 and add 0 to the quotient

$$\begin{array}{l}\phantom{7979)}00\phantom{4}\\7979\overline{)51000000}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}00\phantom{5}\\7979\overline{)51000000}\\\end{array}$$

Since 510 is less than 7979, use the next digit 0 from dividend 51000000 and add 0 to the quotient

$$\begin{array}{l}\phantom{7979)}000\phantom{6}\\7979\overline{)51000000}\\\end{array}$$

Use the 4^{th} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}000\phantom{7}\\7979\overline{)51000000}\\\end{array}$$

Since 5100 is less than 7979, use the next digit 0 from dividend 51000000 and add 0 to the quotient

$$\begin{array}{l}\phantom{7979)}0000\phantom{8}\\7979\overline{)51000000}\\\end{array}$$

Use the 5^{th} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}0000\phantom{9}\\7979\overline{)51000000}\\\end{array}$$

Find closest multiple of 7979 to 51000. We see that 6 \times 7979 = 47874 is the nearest. Now subtract 47874 from 51000 to get reminder 3126. Add 6 to quotient.

$$\begin{array}{l}\phantom{7979)}00006\phantom{10}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}3126\\\end{array}$$

Use the 6^{th} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}00006\phantom{11}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\end{array}$$

Find closest multiple of 7979 to 31260. We see that 3 \times 7979 = 23937 is the nearest. Now subtract 23937 from 31260 to get reminder 7323. Add 3 to quotient.

$$\begin{array}{l}\phantom{7979)}000063\phantom{12}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\phantom{7979)}\underline{\phantom{9}23937\phantom{99}}\\\phantom{7979)99}7323\\\end{array}$$

Use the 7^{th} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}000063\phantom{13}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\phantom{7979)}\underline{\phantom{9}23937\phantom{99}}\\\phantom{7979)99}73230\\\end{array}$$

Find closest multiple of 7979 to 73230. We see that 9 \times 7979 = 71811 is the nearest. Now subtract 71811 from 73230 to get reminder 1419. Add 9 to quotient.

$$\begin{array}{l}\phantom{7979)}0000639\phantom{14}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\phantom{7979)}\underline{\phantom{9}23937\phantom{99}}\\\phantom{7979)99}73230\\\phantom{7979)}\underline{\phantom{99}71811\phantom{9}}\\\phantom{7979)999}1419\\\end{array}$$

Use the 8^{th} digit 0 from dividend 51000000

$$\begin{array}{l}\phantom{7979)}0000639\phantom{15}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\phantom{7979)}\underline{\phantom{9}23937\phantom{99}}\\\phantom{7979)99}73230\\\phantom{7979)}\underline{\phantom{99}71811\phantom{9}}\\\phantom{7979)999}14190\\\end{array}$$

Find closest multiple of 7979 to 14190. We see that 1 \times 7979 = 7979 is the nearest. Now subtract 7979 from 14190 to get reminder 6211. Add 1 to quotient.

$$\begin{array}{l}\phantom{7979)}00006391\phantom{16}\\7979\overline{)51000000}\\\phantom{7979)}\underline{\phantom{}47874\phantom{999}}\\\phantom{7979)9}31260\\\phantom{7979)}\underline{\phantom{9}23937\phantom{99}}\\\phantom{7979)99}73230\\\phantom{7979)}\underline{\phantom{99}71811\phantom{9}}\\\phantom{7979)999}14190\\\phantom{7979)}\underline{\phantom{9999}7979\phantom{}}\\\phantom{7979)9999}6211\\\end{array}$$

Since 6211 is less than 7979, stop the division. The reminder is 6211. The topmost line 00006391 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 6391.

$$\text{Quotient: }6391 \text{Reminder: }6211$$

Factor

$$\frac{2 ^ {6} \cdot 3 \cdot 5 ^ {6} \cdot 17}{79 \cdot 101} = 6391\frac{6211}{7979} = 6391.7784183481635$$
