We're dividing 667431 by 26 
The aim is to understand the frequency of 26 in 667431.

On to step 1:
26 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 26

Let's proceed to step 2:
The number 26 fits into 66 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we take 52 away from 66, we end up with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 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
Subtract 130 from 147 to get 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 26

Moving on to step 4:
The number 26 fits into 174 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 256.0
If we take 156 away from 174, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 26

Let's proceed to step 5:
The number 26 fits into 183 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 2567.0
Subtracting 182 from 183 leaves us with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 26

Moving on to step 6:
11 divided by 26 is 0 with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 25670.0
Subtracting 0 from 11 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
26 goes into 110 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 25670.4
Subtracting 104 from 110 leaves us with 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 8:
When dividing 60 by 26, we get 2 with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25670.42
Subtracting 52 from 60 leaves us 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.

Let's proceed to step 9:
80 divided by 26 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 25670.423
If we subtract 78 from 80, we 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.

Advancing to step 10:
When dividing 20 by 26, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 25670.423
The remainder is 20 after subtracting 0 from 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 11:
When dividing 200 by 26, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 25670.42307
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.

Going ahead to step 12:
180 divided by 26 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 25670.423076
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.

Going ahead to step 13:
The number 26 fits into 240 9 times, leaving a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 25670.4230769
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.

Step 14:
60 divided by 26 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 25670.42307692
If we take 52 away from 60, 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.

The final result is 25670.42307692 with a remainder of 8e-09.
