453534 ÷ 13 
The aim is to understand the frequency of 13 in 453534.

Moving on to step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 13

Let's proceed to step 2:
The number 13 fits into 45 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 39 from 45 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 13

Advancing to step 3:
63 divided by 13 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 52 from 63 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 13

Going ahead to step 4:
115 divided by 13 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 348.0
Subtract 104 from 115 to get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 13

Step 5:
113 divided by 13 is 8 with a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 3488.0
If we subtract 104 from 113, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 13

Advancing to step 6:
The number 13 fits into 94 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 34887.0
Subtracting 91 from 94 leaves us 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.

Let's proceed to step 7:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 34887.2
If we take 26 away from 30, we end up 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.

Advancing to step 8:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 34887.23
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.

Moving on to step 9:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 34887.23
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 10:
If we divide 100 by 13, we get 7 and a remainder of 9.
The next digit of our result is 7. 
Result so far: 34887.2307
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.

On to step 11:
90 divided by 13 is 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 34887.23076
If we subtract 78 from 90, we get 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 12:
If we divide 120 by 13, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 34887.230769
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.

Advancing to step 13:
13 goes into 30 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 34887.2307692
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.

On to step 14:
If we divide 40 by 13, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 34887.23076923
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.

The final outcome is 34887.23076923, with a leftover of 1e-09.
