We're dividing 728176 by 13 
The aim is to understand the frequency of 13 in 728176.

Advancing to step 1:
13 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 13

Advancing to step 2:
13 can be fit into 72 5 times, resulting in a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 65 from 72, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 13

Going ahead to step 3:
The number 13 fits into 78 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 78 from 78 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 13

Step 4:
13 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 560.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 13

On to step 5:
13 goes into 17 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 5601.0
Subtract 13 from 17 to get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 13

Advancing to step 6:
46 divided by 13 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 56013.0
Deduct 39 from 46 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 56013.5
If we take 65 away from 70, we end up 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.

Moving on to step 8:
13 can be fit into 50 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 56013.53
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 56013.538
Deduct 104 from 110 and we're left 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.

Going ahead to step 10:
When dividing 60 by 13, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 56013.5384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 56013.53846
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.

Let's proceed to step 12:
13 goes into 20 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 56013.538461
If we take 13 away from 20, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 56013.5384615
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 13 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 56013.53846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 56013.53846153 with a remaining 1.1e-08.
