We're dividing 39999025 by 26 
The aim is to understand the frequency of 26 in 39999025.

Advancing to step 1:
The number 26 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 26

Step 2:
26 can be fit into 39 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 26 from 39 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 26

Let's proceed to step 3:
If we divide 139 by 26, we get 5 and a remainder of 9.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 130 from 139 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 26

Step 4:
26 goes into 99 3 times with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 153.0
The remainder is 21 after subtracting 78 from 99.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 26

On to step 5:
26 can be fit into 219 8 times, resulting in a remainder of 11.
The next digit of our result is 8. 
Result so far: 1538.0
If we take 208 away from 219, we end up with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 26

Step 6:
The number 26 fits into 110 4 times, leaving a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 15384.0
If we take 104 away from 110, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 26

On to step 7:
62 divided by 26 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 153842.0
If we take 52 away from 62, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 26

Step 8:
26 can be fit into 105 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 1538424.0
Deduct 104 from 105 and we're left 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.

On to step 9:
10 divided by 26 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1538424.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
When dividing 100 by 26, we get 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 1538424.03
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
26 goes into 220 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 1538424.038
If we take 208 away from 220, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
26 can be fit into 120 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1538424.0384
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
When dividing 160 by 26, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 1538424.03846
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
If we divide 40 by 26, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1538424.038461
If we take 26 away from 40, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 15:
140 divided by 26 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1538424.0384615
Deduct 130 from 140 and we're left 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.

Step 16:
26 goes into 100 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 1538424.03846153
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 1538424.03846153 with a remainder of 2.2e-08.
