We're dividing 615208 by 13 
The aim is to understand the frequency of 13 in 615208.

Step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 13

Moving on to step 2:
61 divided by 13 is 4 with a remainder of 9.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 9 after subtracting 52 from 61.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 13

Advancing to step 3:
If we divide 95 by 13, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 91 from 95, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 13

Step 4:
13 goes into 42 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 473.0
If we take 39 away from 42, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 13

Advancing to step 5:
When dividing 30 by 13, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 4732.0
Deduct 26 from 30 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 13

Step 6:
If we divide 48 by 13, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 47323.0
If we take 39 away from 48, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 47323.6
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 47323.69
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 13 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 47323.692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
If we divide 40 by 13, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 47323.6923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 47323.6923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
When dividing 100 by 13, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 47323.692307
Subtracting 91 from 100 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 47323.6923076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
If we divide 120 by 13, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 47323.69230769
Subtracting 117 from 120 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 47323.69230769 with a remainder of 3e-09.
