We're dividing 667583 by 26 
The aim is to understand the frequency of 26 in 667583.

Step 1:
26 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 26

Let's proceed to step 2:
The number 26 fits into 66 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 14 after subtracting 52 from 66.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 26

Advancing to step 3:
If we divide 147 by 26, we get 5 and a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 25.0
Subtracting 130 from 147 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 26

Moving on to step 4:
If we divide 175 by 26, we get 6 and a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 256.0
Subtracting 156 from 175 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 26

Let's proceed to step 5:
26 goes into 198 7 times with a remainder of 16.
The next digit of our result is 7. 
Result so far: 2567.0
Subtracting 182 from 198 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 26

Going ahead to step 6:
26 goes into 163 6 times with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 25676.0
Subtracting 156 from 163 leaves us 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.

Moving on to 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: 25676.2
If we subtract 52 from 70, we 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.

Let's proceed to step 8:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 25676.26
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.

Going ahead to step 9:
If we divide 240 by 26, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 25676.269
If we subtract 234 from 240, we 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.

On to step 10:
26 goes into 60 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25676.2692
Subtract 52 from 60 to 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.

Moving on to step 11:
26 can be fit into 80 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 25676.26923
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.

Going ahead to step 12:
20 divided by 26 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25676.26923
If we subtract 0 from 20, we 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.

Moving on to step 13:
If we divide 200 by 26, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 25676.2692307
Subtract 182 from 200 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.

Moving on to step 14:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 25676.26923076
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 25676.26923076 and a remainder of 2.4e-08.
