We're dividing 867028 by 13 
The aim is to understand the frequency of 13 in 867028.

Step 1:
13 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 13

Step 2:
When dividing 86 by 13, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 78 from 86, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 13

Let's proceed to step 3:
13 can be fit into 87 6 times, resulting in a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we subtract 78 from 87, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 13

On to step 4:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 666.0
Deduct 78 from 90 and we're left with 12.
Take the next digit (2) from the dividend and append it to 12, then repeat: 122 / 13

Let's proceed to step 5:
The number 13 fits into 122 9 times, leaving a remainder of 5.
The next digit of our result is 9. 
Result so far: 6669.0
Subtracting 117 from 122 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 13

On to step 6:
13 can be fit into 58 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 66694.0
Deduct 52 from 58 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.

Step 7:
13 goes into 60 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 66694.4
If we take 52 away from 60, we end up 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.

Step 8:
If we divide 80 by 13, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66694.46
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
13 goes into 20 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 66694.461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 66694.4615
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.

Let's proceed to step 11:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 66694.46153
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.

Step 12:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 66694.461538
If we subtract 104 from 110, we get 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 13:
60 divided by 13 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 66694.4615384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
13 goes into 80 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 66694.46153846
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.

In conclusion, the division gives 66694.46153846 with a balance of 2e-09.
