669745 ÷ 26 
The aim is to understand the frequency of 26 in 669745.

Let's proceed to step 1:
If we divide 6 by 26, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 26

Step 2:
26 can be fit into 66 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 52 from 66 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 26

On to step 3:
26 can be fit into 149 5 times, resulting in a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 130 from 149, we get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 26

Going ahead to step 4:
26 can be fit into 197 7 times, resulting in a remainder of 15.
The next digit of our result is 7. 
Result so far: 257.0
Subtracting 182 from 197 leaves us with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 26

Advancing to step 5:
The number 26 fits into 154 5 times, leaving a remainder of 24.
The next digit of our result is 5. 
Result so far: 2575.0
Subtract 130 from 154 to get 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 26

Let's proceed to step 6:
When dividing 245 by 26, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 25759.0
If we subtract 234 from 245, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 26, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 25759.4
If we take 104 away from 110, we end up 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.

Let's proceed to step 8:
60 divided by 26 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 25759.42
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.

Moving on to step 9:
26 can be fit into 80 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 25759.423
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.

On to step 10:
The number 26 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 25759.423
Deduct 0 from 20 and we're left 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.

Step 11:
When dividing 200 by 26, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 25759.42307
If we subtract 182 from 200, 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.

On to step 12:
The number 26 fits into 180 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 25759.423076
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.

Let's proceed to step 13:
26 goes into 240 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 25759.4230769
Deduct 234 from 240 and we're left 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.

Let's proceed to step 14:
60 divided by 26 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 25759.42307692
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.

Our division results in 25759.42307692 with a remaining 8e-09.
