We look at the division of 417619 by 26 
The aim is to understand the frequency of 26 in 417619.

On to step 1:
The number 26 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 26

Going ahead to step 2:
The number 26 fits into 41 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 26 from 41 leaves us with 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 26

Moving on to step 3:
If we divide 157 by 26, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 156 away from 157, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 26

Going ahead to step 4:
16 divided by 26 is 0 with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
If we subtract 0 from 16, we get 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 26

Moving on to step 5:
26 can be fit into 161 6 times, resulting in a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 1606.0
If we subtract 156 from 161, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 26

Advancing to step 6:
The number 26 fits into 59 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 16062.0
If we take 52 away from 59, we end up 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.

Let's proceed to step 7:
70 divided by 26 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 16062.2
Deduct 52 from 70 and we're left 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.

Advancing to step 8:
26 goes into 180 6 times with a remainder of 24.
The next digit of our result is 6. 
Result so far: 16062.26
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.

Let's proceed to step 9:
If we divide 240 by 26, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 16062.269
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
When dividing 60 by 26, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 16062.2692
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
When dividing 80 by 26, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 16062.26923
Subtract 78 from 80 to 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.

Let's proceed to step 12:
When dividing 20 by 26, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 16062.26923
Subtracting 0 from 20 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.

Going ahead to step 13:
26 can be fit into 200 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 16062.2692307
If we take 182 away from 200, we end up 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.

Step 14:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 16062.26923076
If we subtract 156 from 180, we 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 16062.26923076 with a remainder of 2.4e-08.
