504017 ÷ 26 
The aim is to understand the frequency of 26 in 504017.

Step 1:
26 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 26

Advancing to step 2:
If we divide 50 by 26, we get 1 and a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
If we take 26 away from 50, we end up with 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 26

Step 3:
If we divide 244 by 26, we get 9 and a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 234 from 244, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 26

Advancing to step 4:
26 can be fit into 100 3 times, resulting in a remainder of 22.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 78 from 100 leaves us with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 26

Going ahead to step 5:
26 can be fit into 221 8 times, resulting in a remainder of 13.
The next digit of our result is 8. 
Result so far: 1938.0
Subtract 208 from 221 to get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 26

On to step 6:
The number 26 fits into 137 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 19385.0
If we take 130 away from 137, 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.

Step 7:
If we divide 70 by 26, we get 2 and a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 19385.2
Subtract 52 from 70 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 26, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 19385.26
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.

Going ahead to step 9:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 19385.269
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.

Moving on to step 10:
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: 19385.2692
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.

Going ahead to step 11:
26 goes into 80 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 19385.26923
If we take 78 away from 80, we end up 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.

Going ahead to step 12:
When dividing 20 by 26, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 19385.26923
If we take 0 away from 20, we end up 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.

Advancing to step 13:
When dividing 200 by 26, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 19385.2692307
Subtracting 182 from 200 leaves us 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.

On to step 14:
26 goes into 180 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 19385.26923076
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.

The quotient of the division is 19385.26923076, and the remainder is 2.4e-08.
