We look at the division of 672610 by 13 
The aim is to understand the frequency of 13 in 672610.

Step 1:
13 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 13

Step 2:
The number 13 fits into 67 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 65 from 67 and we're left with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 13

Step 3:
The number 13 fits into 22 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 51.0
If we subtract 13 from 22, we get 9.
Grab the next digit (6) from the dividend, add it to 9, then carry on: 96 / 13

Moving on to step 4:
13 goes into 96 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 517.0
Subtracting 91 from 96 leaves us with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 13

Advancing to step 5:
51 divided by 13 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 5173.0
Subtracting 39 from 51 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 13

Step 6:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 51739.0
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.

Advancing to step 7:
30 divided by 13 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 51739.2
Deduct 26 from 30 and we're left 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.

Advancing to step 8:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 51739.23
If we subtract 39 from 40, we 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.

Moving on to step 9:
If we divide 10 by 13, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 51739.23
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.

Let's proceed to step 10:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 51739.2307
If we subtract 91 from 100, 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.

Advancing to step 11:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 51739.23076
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.

Let's proceed to step 12:
When dividing 120 by 13, we get 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 51739.230769
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.

Moving on to step 13:
If we divide 30 by 13, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 51739.2307692
Subtracting 26 from 30 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.

Step 14:
If we divide 40 by 13, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 51739.23076923
Subtracting 39 from 40 leaves us 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.

In conclusion, the division gives 51739.23076923 with a balance of 1e-09.
