We're dividing 125988 by 26 
The aim is to understand the frequency of 26 in 125988.

Advancing to step 1:
26 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 26

Let's proceed to step 2:
26 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 26

Step 3:
When dividing 125 by 26, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 104 from 125 leaves us with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 26

On to step 4:
When dividing 219 by 26, we get 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 48.0
The remainder is 11 after subtracting 208 from 219.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 26

Going ahead to step 5:
26 can be fit into 118 4 times, resulting in a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 484.0
Subtracting 104 from 118 leaves us with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 26

Step 6:
When dividing 148 by 26, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 4845.0
Subtracting 130 from 148 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 4845.6
Deduct 156 from 180 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 8:
When dividing 240 by 26, we get 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4845.69
Deduct 234 from 240 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.

Advancing to step 9:
26 can be fit into 60 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 4845.692
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 26 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 4845.6923
The remainder is 2 after subtracting 78 from 80.
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 11:
If we divide 20 by 26, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4845.6923
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
26 goes into 200 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 4845.692307
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 4845.6923076
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 14:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 4845.69230769
Subtract 234 from 240 to 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.

The final outcome is 4845.69230769, with a leftover of 6e-09.
