We look at the division of 670367 by 13 
The aim is to understand the frequency of 13 in 670367.

Advancing to step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 13

Step 2:
13 goes into 67 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 65 from 67 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 13

Advancing to step 3:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 51.0
If we take 13 away from 20, we end up with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 13

Let's proceed to step 4:
73 divided by 13 is 5 with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 515.0
The remainder is 8 after subtracting 65 from 73.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 13

Step 5:
86 divided by 13 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 5156.0
Subtract 78 from 86 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 13

Going ahead to step 6:
87 divided by 13 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 51566.0
The remainder is 9 after subtracting 78 from 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 51566.6
Subtract 78 from 90 to 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.

Let's proceed to step 8:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 51566.69
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
If we divide 30 by 13, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 51566.692
If we subtract 26 from 30, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
13 goes into 40 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 51566.6923
Subtract 39 from 40 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 51566.6923
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
100 divided by 13 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 51566.692307
Deduct 91 from 100 and we're left 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.

Advancing to step 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 51566.6923076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 14:
120 divided by 13 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 51566.69230769
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 51566.69230769 with a remainder of 3e-09.
