We look at the division of 980672 by 13 
The aim is to understand the frequency of 13 in 980672.

Step 1:
13 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 13

On to step 2:
If we divide 98 by 13, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 91 from 98 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 13

Let's proceed to step 3:
When dividing 70 by 13, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 75.0
If we subtract 65 from 70, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 13

On to step 4:
56 divided by 13 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 754.0
Subtracting 52 from 56 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 13

Moving on to step 5:
13 can be fit into 47 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 7543.0
The remainder is 8 after subtracting 39 from 47.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 13

Advancing to step 6:
82 divided by 13 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 75436.0
Deduct 78 from 82 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.

On to step 7:
When dividing 40 by 13, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 75436.3
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 75436.3
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.

Going ahead to step 9:
100 divided by 13 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 75436.307
Subtract 91 from 100 to 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 10:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 75436.3076
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.

Let's proceed to step 11:
13 goes into 120 9 times with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 75436.30769
The remainder is 3 after subtracting 117 from 120.
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 12:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 75436.307692
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.

On to step 13:
13 goes into 40 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 75436.3076923
The remainder is 1 after subtracting 39 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
13 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 75436.3076923
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 75436.3076923 with a balance of 1e-08.
