We look at the division of 25203554 by 26 
The aim is to understand the frequency of 26 in 25203554.

Step 1:
The number 26 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 26

On to step 2:
26 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 26

Step 3:
26 goes into 252 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 234 from 252, we get 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 26

Step 4:
When dividing 180 by 26, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 96.0
Subtracting 156 from 180 leaves us with 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 26

Moving on to step 5:
26 goes into 243 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 969.0
Subtracting 234 from 243 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 26

Advancing to step 6:
The number 26 fits into 95 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 9693.0
Subtracting 78 from 95 leaves us with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 26

Moving on to step 7:
If we divide 175 by 26, we get 6 and a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 96936.0
Subtract 156 from 175 to get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 26

Step 8:
The number 26 fits into 194 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 969367.0
The remainder is 12 after subtracting 182 from 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
26 goes into 120 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 969367.4
If we subtract 104 from 120, we 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.

Let's proceed to step 10:
26 can be fit into 160 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 969367.46
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
26 goes into 40 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 969367.461
If we subtract 26 from 40, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
26 goes into 140 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 969367.4615
Subtracting 130 from 140 leaves us 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.

On to step 13:
26 can be fit into 100 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 969367.46153
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
26 can be fit into 220 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 969367.461538
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 15:
If we divide 120 by 26, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 969367.4615384
The remainder is 16 after subtracting 104 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 16:
The number 26 fits into 160 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 969367.46153846
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.

Our division results in 969367.46153846 with a remaining 4e-09.
