We look at the division of 501819 by 26 
The aim is to understand the frequency of 26 in 501819.

Moving on to step 1:
If we divide 5 by 26, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 26

Let's proceed to step 2:
If we divide 50 by 26, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 26 from 50 to get 24.
Fetch the next digit (1) from the dividend, attach it to 24 and continue: 241 / 26

Going ahead to step 3:
If we divide 241 by 26, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 234 from 241 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 26

Going ahead to step 4:
If we divide 78 by 26, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 193.0
If we take 78 away from 78, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 26

Advancing to step 5:
26 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 1930.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 26

On to step 6:
26 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 19300.0
If we take 0 away from 19, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
26 goes into 190 7 times with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 19300.7
If we take 182 away from 190, we end up 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.

Advancing to step 8:
When dividing 80 by 26, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 19300.73
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 26 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 19300.73
Subtract 0 from 20 to 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.

Step 10:
If we divide 200 by 26, we get 7 and a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 19300.7307
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.

Let's proceed to step 11:
When dividing 180 by 26, we get 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 19300.73076
If we take 156 away from 180, we end up 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 12:
When dividing 240 by 26, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 19300.730769
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.

Going ahead to step 13:
If we divide 60 by 26, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 19300.7307692
Deduct 52 from 60 and we're left 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 14:
26 goes into 80 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 19300.73076923
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 19300.73076923 with a balance of 2e-09.
