We're dividing 274281 by 13 
The aim is to understand the frequency of 13 in 274281.

Let's proceed to step 1:
The number 13 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 13

Going ahead to step 2:
27 divided by 13 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 26 from 27 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 13

Moving on to step 3:
14 divided by 13 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 13 from 14 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 13

Step 4:
When dividing 12 by 13, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 13

Advancing to step 5:
128 divided by 13 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 2109.0
If we subtract 117 from 128, we get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 13

Moving on to step 6:
If we divide 111 by 13, we get 8 and a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 21098.0
Subtracting 104 from 111 leaves us with 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 7:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21098.5
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.

Advancing to step 8:
When dividing 50 by 13, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 21098.53
The remainder is 11 after subtracting 39 from 50.
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 9:
When dividing 110 by 13, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 21098.538
If we subtract 104 from 110, we get 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 10:
When dividing 60 by 13, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 21098.5384
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.

On to step 11:
The number 13 fits into 80 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 21098.53846
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 12:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 21098.538461
If we subtract 13 from 20, we 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.

Let's proceed to step 13:
70 divided by 13 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21098.5384615
Deduct 65 from 70 and we're left 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.

On to step 14:
13 can be fit into 50 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 21098.53846153
Deduct 39 from 50 and we're left 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.

In conclusion, the division gives 21098.53846153 with a balance of 1.1e-08.
