We're dividing 79839900 by 868 
The aim is to understand the frequency of 868 in 79839900.

Advancing to step 1:
7 divided by 868 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 868

Going ahead to step 2:
79 divided by 868 is 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 868

On to step 3:
The number 868 fits into 798 0 times, leaving a remainder of 798.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 798, we get 798.
Bring next digit (3) of the dividend behind the 798 and repeat the process: 7983 / 868

Going ahead to step 4:
868 can be fit into 7983 9 times, resulting in a remainder of 171.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7812 from 7983 to get 171.
Include the next digit (9) from the dividend after 171, then repeat: 1719 / 868

On to step 5:
If we divide 1719 by 868, we get 1 and a remainder of 851.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Subtract 868 from 1719 to get 851.
Fetch the next digit (9) from the dividend, attach it to 851 and continue: 8519 / 868

Advancing to step 6:
The number 868 fits into 8519 9 times, leaving a remainder of 707.
The next digit of our result is 9. 
Result so far: 919.0
If we subtract 7812 from 8519, we get 707.
Take the next digit (0) from the dividend and append it to 707, then repeat: 7070 / 868

Let's proceed to step 7:
7070 divided by 868 is 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 9198.0
Subtract 6944 from 7070 to get 126.
Append the next digit (0) from the dividend to 126 and continue with: 1260 / 868

Let's proceed to step 8:
1260 divided by 868 is 1 with a remainder of 392.
The number 1 becomes the next digit in our result. 
Result so far: 91981.0
Subtracting 868 from 1260 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 9:
868 goes into 3920 4 times with a remainder of 448.
Put 4 as the next digit of the answer. 
Result so far: 91981.4
Subtract 3472 from 3920 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 10:
If we divide 4480 by 868, we get 5 and a remainder of 140.
The next digit of our result is 5. 
Result so far: 91981.45
The remainder is 140 after subtracting 4340 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 11:
The number 868 fits into 1400 1 times, leaving a remainder of 532.
Use 1 as the next digit of our solution. 
Result so far: 91981.451
If we take 868 away from 1400, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Advancing to step 12:
When dividing 5320 by 868, we get 6 with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 91981.4516
The remainder is 112 after subtracting 5208 from 5320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 13:
868 can be fit into 1120 1 times, resulting in a remainder of 252.
Record the quotient 1 as the next digit in the result. 
Result so far: 91981.45161
Subtract 868 from 1120 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 14:
2520 divided by 868 is 2 with a remainder of 784.
Record the quotient 2 as the next digit in the result. 
Result so far: 91981.451612
Subtract 1736 from 2520 to get 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

Step 15:
The number 868 fits into 7840 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 91981.4516129
If we subtract 7812 from 7840, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 16:
280 divided by 868 is 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 91981.4516129
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 91981.4516129 and a remainder of 2.8e-07.
