We look at the division of 634424 by 13 
The aim is to understand the frequency of 13 in 634424.

Moving on to step 1:
If we divide 6 by 13, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 13

Let's proceed to step 2:
13 can be fit into 63 4 times, resulting in a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 52 from 63 leaves us with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 13

Advancing to step 3:
13 goes into 114 8 times with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtract 104 from 114 to get 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 13

Moving on to step 4:
104 divided by 13 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 488.0
Subtracting 104 from 104 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 13

Let's proceed to step 5:
13 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 4880.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 13

On to step 6:
The number 13 fits into 24 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 48801.0
Subtracting 13 from 24 leaves us 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.

Moving on to step 7:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 48801.8
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 13, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 48801.84
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 48801.846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 48801.8461
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.

On to step 11:
13 can be fit into 70 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 48801.84615
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 12:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 48801.846153
Subtract 39 from 50 to get 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 13:
110 divided by 13 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 48801.8461538
Deduct 104 from 110 and we're left 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.

Going ahead to step 14:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 48801.84615384
Subtracting 52 from 60 leaves us 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.

The final result is 48801.84615384 with a remainder of 8e-09.
