We look at the division of 831689 by 79 
The aim is to understand the frequency of 79 in 831689.

Advancing to step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 79

Advancing to step 2:
If we divide 83 by 79, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 79 from 83, we get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 79

Going ahead to step 3:
If we divide 41 by 79, we get 0 and a remainder of 41.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 41 after subtracting 0 from 41.
Fetch the next digit (6) from the dividend, attach it to 41 and continue: 416 / 79

Going ahead to step 4:
79 can be fit into 416 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we subtract 395 from 416, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 79

On to step 5:
The number 79 fits into 218 2 times, leaving a remainder of 60.
The next digit of our result is 2. 
Result so far: 1052.0
Subtracting 158 from 218 leaves us with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 79

On to step 6:
79 goes into 609 7 times with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 10527.0
The remainder is 56 after subtracting 553 from 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
560 divided by 79 is 7 with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 10527.7
If we take 553 away from 560, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
79 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10527.7
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 9:
79 can be fit into 700 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 10527.708
The remainder is 68 after subtracting 632 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 10:
When dividing 680 by 79, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10527.7088
Subtract 632 from 680 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

In conclusion, the division gives 10527.7088 with a balance of 0.00048.
