We look at the division of 852213 by 79 
The aim is to understand the frequency of 79 in 852213.

Going ahead to step 1:
79 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 79

Going ahead to step 2:
79 goes into 85 1 times with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 79 away from 85, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 79

Moving on to step 3:
79 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 79

Moving on to step 4:
If we divide 622 by 79, we get 7 and a remainder of 69.
The next digit of our result is 7. 
Result so far: 107.0
If we subtract 553 from 622, we get 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 79

On to step 5:
79 goes into 691 8 times with a remainder of 59.
Put 8 as the next digit of the answer. 
Result so far: 1078.0
Subtracting 632 from 691 leaves us with 59.
Append the next digit (3) from the dividend to 59 and continue with: 593 / 79

Moving on to step 6:
If we divide 593 by 79, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 10787.0
Subtracting 553 from 593 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
79 can be fit into 400 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10787.5
Subtracting 395 from 400 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
When dividing 50 by 79, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10787.5
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 9:
If we divide 500 by 79, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 10787.506
Deduct 474 from 500 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 79 is 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 10787.5063
If we subtract 237 from 260, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
230 divided by 79 is 2 with a remainder of 72.
The next digit of our result is 2. 
Result so far: 10787.50632
Subtracting 158 from 230 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
79 can be fit into 720 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 10787.506329
If we subtract 711 from 720, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
90 divided by 79 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 10787.5063291
The remainder is 11 after subtracting 79 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 14:
When dividing 110 by 79, we get 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 10787.50632911
Subtracting 79 from 110 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 10787.50632911, with a leftover of 3.1e-08.
