We're dividing 520209 by 79 
The aim is to understand the frequency of 79 in 520209.

Advancing to step 1:
When dividing 5 by 79, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 79

On to step 2:
52 divided by 79 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 79

Let's proceed to step 3:
79 goes into 520 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 474 from 520 leaves us with 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 79

Going ahead to step 4:
If we divide 462 by 79, we get 5 and a remainder of 67.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 395 away from 462, we end up with 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 79

Step 5:
79 goes into 670 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 658.0
The remainder is 38 after subtracting 632 from 670.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 79

Moving on to step 6:
When dividing 389 by 79, we get 4 with a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 6584.0
Subtracting 316 from 389 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
When dividing 730 by 79, we get 9 with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 6584.9
Subtracting 711 from 730 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
If we divide 190 by 79, we get 2 and a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 6584.92
Subtracting 158 from 190 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
79 can be fit into 320 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 6584.924
Subtracting 316 from 320 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
79 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 6584.924
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
If we divide 400 by 79, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6584.92405
If we subtract 395 from 400, we get 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 12:
79 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 6584.92405
If we subtract 0 from 50, we 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.

On to step 13:
79 can be fit into 500 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 6584.9240506
Subtract 474 from 500 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 14:
79 goes into 260 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 6584.92405063
The remainder is 23 after subtracting 237 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final result is 6584.92405063 with a remainder of 2.3e-08.
