Let's divide 33141657 by 13
The aim is to understand the frequency of 13 in 33141657.

Step 1:
When dividing 3 by 13, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 13

Going ahead to step 2:
13 can be fit into 33 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 26 away from 33, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 13

Advancing to step 3:
The number 13 fits into 71 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 6 after subtracting 65 from 71.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 13

Step 4:
64 divided by 13 is 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Deduct 52 from 64 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 13

Advancing to step 5:
121 divided by 13 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 2549.0
Subtracting 117 from 121 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 13

Moving on to step 6:
46 divided by 13 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 25493.0
The remainder is 7 after subtracting 39 from 46.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 13

Advancing to step 7:
13 goes into 75 5 times with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 254935.0
If we subtract 65 from 75, we get 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 13

Advancing to step 8:
The number 13 fits into 107 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 2549358.0
Deduct 104 from 107 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.

Advancing to step 9:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2549358.2
The remainder is 4 after subtracting 26 from 30.
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:
13 goes into 40 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 2549358.23
Subtracting 39 from 40 leaves us with 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 11:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2549358.23
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 12:
13 can be fit into 100 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 2549358.2307
The remainder is 9 after subtracting 91 from 100.
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:
13 goes into 90 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 2549358.23076
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 14:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 2549358.230769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 15:
13 goes into 30 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2549358.2307692
Subtracting 26 from 30 leaves us 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.

Going ahead to step 16:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 2549358.23076923
If we take 39 away from 40, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 2549358.23076923 and a remainder of 1e-09.
