We're dividing 17825828 by 26 
The aim is to understand the frequency of 26 in 17825828.

Step 1:
The number 26 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 26

Step 2:
26 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 26

Moving on to step 3:
26 goes into 178 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 156 from 178, we get 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 26

Step 4:
The number 26 fits into 222 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 68.0
If we subtract 208 from 222, we get 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 26

Going ahead to step 5:
The number 26 fits into 145 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 685.0
The remainder is 15 after subtracting 130 from 145.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 26

Advancing to step 6:
26 can be fit into 158 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 6856.0
The remainder is 2 after subtracting 156 from 158.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 26

Let's proceed to step 7:
If we divide 22 by 26, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 68560.0
Deduct 0 from 22 and we're left with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 26

Step 8:
If we divide 228 by 26, we get 8 and a remainder of 20.
The next digit of our result is 8. 
Result so far: 685608.0
Subtracting 208 from 228 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
The number 26 fits into 200 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 685608.7
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 10:
26 goes into 180 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 685608.76
Subtracting 156 from 180 leaves us 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.

Let's proceed to step 11:
26 goes into 240 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 685608.769
If we subtract 234 from 240, 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.

Moving on to step 12:
60 divided by 26 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 685608.7692
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.

Going ahead to step 13:
26 goes into 80 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 685608.76923
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.

Moving on to step 14:
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: 685608.76923
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 15:
26 can be fit into 200 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 685608.7692307
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.

Going ahead to step 16:
26 goes into 180 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 685608.76923076
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.

The final result is 685608.76923076 with a remainder of 2.4e-08.
