We look at the division of 611019 by 13 
The aim is to understand the frequency of 13 in 611019.

Advancing to step 1:
The number 13 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 13

Step 2:
13 can be fit into 61 4 times, resulting in 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.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 13

Going ahead to step 3:
If we divide 91 by 13, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 47.0
Deduct 91 from 91 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 13

Step 4:
13 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 470.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 13

On to step 5:
1 divided by 13 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 4700.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 13

Step 6:
13 goes into 19 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 47001.0
Subtracting 13 from 19 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
If we divide 60 by 13, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 47001.4
Subtract 52 from 60 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
80 divided by 13 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 47001.46
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 47001.461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
When dividing 70 by 13, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 47001.4615
Subtracting 65 from 70 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.

Step 11:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 47001.46153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 12:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 47001.461538
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
The number 13 fits into 60 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 47001.4615384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
13 goes into 80 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 47001.46153846
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 47001.46153846 with a remainder of 2e-09.
