We look at the division of 33562005 by 13 
The aim is to understand the frequency of 13 in 33562005.

On to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 13

Advancing to step 2:
When dividing 33 by 13, we get 2 with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 26 from 33 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 13

Step 3:
If we divide 75 by 13, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
The remainder is 10 after subtracting 65 from 75.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 13

Let's proceed to step 4:
13 goes into 106 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Subtract 104 from 106 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 13

Advancing to step 5:
When dividing 22 by 13, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 2581.0
The remainder is 9 after subtracting 13 from 22.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 13

Moving on to step 6:
The number 13 fits into 90 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 25816.0
If we subtract 78 from 90, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 13

Step 7:
120 divided by 13 is 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 258169.0
Deduct 117 from 120 and we're left with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 13

Advancing to step 8:
When dividing 35 by 13, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2581692.0
Subtract 26 from 35 to 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.

On to step 9:
If we divide 90 by 13, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 2581692.6
The remainder is 12 after subtracting 78 from 90.
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 10:
If we divide 120 by 13, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2581692.69
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.

On to step 11:
The number 13 fits into 30 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 2581692.692
Subtract 26 from 30 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 13 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2581692.6923
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.

Advancing to step 13:
13 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 2581692.6923
If we take 0 away from 10, we end up 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.

Advancing to step 14:
When dividing 100 by 13, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 2581692.692307
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 15:
90 divided by 13 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 2581692.6923076
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.

On to step 16:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2581692.69230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 2581692.69230769 with a remaining 3e-09.
