We're dividing 487726 by 13 
The aim is to understand the frequency of 13 in 487726.

Going ahead to step 1:
13 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 13

Going ahead to step 2:
13 goes into 48 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 39 away from 48, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 13

Let's proceed to step 3:
13 can be fit into 97 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 6 after subtracting 91 from 97.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 13

Going ahead to step 4:
67 divided by 13 is 5 with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 375.0
Deduct 65 from 67 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 13

Step 5:
13 can be fit into 22 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 3751.0
Deduct 13 from 22 and we're left with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 13

On to step 6:
The number 13 fits into 96 7 times, leaving a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 37517.0
If we subtract 91 from 96, we 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.

Advancing to step 7:
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: 37517.3
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.

Going ahead to step 8:
When dividing 110 by 13, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 37517.38
Subtract 104 from 110 to 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.

On to step 9:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 37517.384
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.

Going ahead to step 10:
80 divided by 13 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 37517.3846
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.

Moving on to step 11:
20 divided by 13 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 37517.38461
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.

Going ahead to step 12:
70 divided by 13 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 37517.384615
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.

Going ahead to step 13:
When dividing 50 by 13, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 37517.3846153
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.

Advancing to step 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
The next digit of our result is 8. 
Result so far: 37517.38461538
Subtracting 104 from 110 leaves us 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.

After the division, we end up with 37517.38461538 and a remainder of 6e-09.
