We look at the division of 468490 by 13 
The aim is to understand the frequency of 13 in 468490.

Advancing to step 1:
13 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 13

Let's proceed to step 2:
If we divide 46 by 13, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 39 from 46 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 13

On to step 3:
13 goes into 78 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtracting 78 from 78 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 13

Moving on to step 4:
4 divided by 13 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 360.0
If we take 0 away from 4, we end up with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 13

Moving on to step 5:
13 goes into 49 3 times with a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 3603.0
Subtracting 39 from 49 leaves us with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 13

Step 6:
13 goes into 100 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 36037.0
If we subtract 91 from 100, we 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.

Let's proceed to step 7:
When dividing 90 by 13, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 36037.6
If we take 78 away from 90, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 36037.69
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 13, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 36037.692
Deduct 26 from 30 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.

Step 10:
40 divided by 13 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 36037.6923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
If we divide 10 by 13, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 36037.6923
Deduct 0 from 10 and we're left 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 12:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 36037.692307
If we take 91 away from 100, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 36037.6923076
Deduct 78 from 90 and we're left with 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 14:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 36037.69230769
Deduct 117 from 120 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 36037.69230769 with a remainder of 3e-09.
