Let's divide 486546 by 13
The aim is to understand the frequency of 13 in 486546.

Advancing to step 1:
4 divided by 13 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 13

Let's proceed to step 2:
13 goes into 48 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 39 from 48, we get 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 13

Going ahead to step 3:
13 goes into 96 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 37.0
Subtract 91 from 96 to get 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 13

Step 4:
The number 13 fits into 55 4 times, leaving a remainder of 3.
The next digit of our result is 4. 
Result so far: 374.0
Deduct 52 from 55 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 13

On to step 5:
If we divide 34 by 13, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 3742.0
The remainder is 8 after subtracting 26 from 34.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 13

Step 6:
When dividing 86 by 13, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 37426.0
Deduct 78 from 86 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.

Advancing to step 7:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 37426.6
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 37426.61
Subtracting 13 from 20 leaves us 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.

Moving on to step 9:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37426.615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
13 goes into 50 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 37426.6153
Deduct 39 from 50 and we're left 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 11:
When dividing 110 by 13, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 37426.61538
If we take 104 away from 110, we end up 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 12:
If we divide 60 by 13, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 37426.615384
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 13:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 37426.6153846
If we take 78 away from 80, we end up 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.

Advancing to step 14:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 37426.61538461
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.

In conclusion, the division gives 37426.61538461 with a balance of 7e-09.
