We look at the division of 98079117 by 869 
The aim is to understand the frequency of 869 in 98079117.

Moving on to step 1:
9 divided by 869 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 869

Let's proceed to step 2:
If we divide 98 by 869, we get 0 and a remainder of 98.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 98 and we're left with 98.
Fetch the next digit (0) from the dividend, attach it to 98 and continue: 980 / 869

Advancing to step 3:
When dividing 980 by 869, we get 1 with a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 869 from 980 leaves us with 111.
Bring next digit (7) of the dividend behind the 111 and repeat the process: 1117 / 869

On to step 4:
If we divide 1117 by 869, we get 1 and a remainder of 248.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 869 from 1117 to get 248.
Append the next digit (9) from the dividend to 248 and continue with: 2489 / 869

Step 5:
If we divide 2489 by 869, we get 2 and a remainder of 751.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we subtract 1738 from 2489, we get 751.
Append the next digit (1) from the dividend to 751 and continue with: 7511 / 869

Step 6:
The number 869 fits into 7511 8 times, leaving a remainder of 559.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
If we take 6952 away from 7511, we end up with 559.
Include the next digit (1) from the dividend after 559, then repeat: 5591 / 869

Going ahead to step 7:
The number 869 fits into 5591 6 times, leaving a remainder of 377.
Put 6 as the next digit of the answer. 
Result so far: 11286.0
If we subtract 5214 from 5591, we get 377.
Append the next digit (7) from the dividend to 377 and continue with: 3777 / 869

Step 8:
The number 869 fits into 3777 4 times, leaving a remainder of 301.
Record the quotient 4 as the next digit in the result. 
Result so far: 112864.0
Subtract 3476 from 3777 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Advancing to step 9:
3010 divided by 869 is 3 with a remainder of 403.
Put 3 as the next digit of the answer. 
Result so far: 112864.3
Deduct 2607 from 3010 and we're left with 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Step 10:
The number 869 fits into 4030 4 times, leaving a remainder of 554.
Put 4 as the next digit of the answer. 
Result so far: 112864.34
The remainder is 554 after subtracting 3476 from 4030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

On to step 11:
869 can be fit into 5540 6 times, resulting in a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 112864.346
The remainder is 326 after subtracting 5214 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Moving on to step 12:
The number 869 fits into 3260 3 times, leaving a remainder of 653.
Write down 3 as next digit of the result. 
Result so far: 112864.3463
If we subtract 2607 from 3260, we get 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Let's proceed to step 13:
6530 divided by 869 is 7 with a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 112864.34637
The remainder is 447 after subtracting 6083 from 6530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Moving on to step 14:
If we divide 4470 by 869, we get 5 and a remainder of 125.
The next digit of our result is 5. 
Result so far: 112864.346375
Subtracting 4345 from 4470 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 15:
If we divide 1250 by 869, we get 1 and a remainder of 381.
The number 1 becomes the next digit in our result. 
Result so far: 112864.3463751
Deduct 869 from 1250 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Moving on to step 16:
The number 869 fits into 3810 4 times, leaving a remainder of 334.
Write down 4 as next digit of the result. 
Result so far: 112864.34637514
The remainder is 334 after subtracting 3476 from 3810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final result is 112864.34637514 with a remainder of 3.34e-07.
