397408 divided by 26 
The aim is to understand the frequency of 26 in 397408.

On to step 1:
The number 26 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 26

Step 2:
When dividing 39 by 26, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 26 from 39, we get 13.
Append the next digit (7) from the dividend to 13 and continue with: 137 / 26

Going ahead to step 3:
137 divided by 26 is 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 130 from 137 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 26

Advancing to step 4:
26 can be fit into 74 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
Subtracting 52 from 74 leaves us with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 26

Let's proceed to step 5:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1528.0
The remainder is 12 after subtracting 208 from 220.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 26

Let's proceed to step 6:
26 goes into 128 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15284.0
The remainder is 24 after subtracting 104 from 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
The number 26 fits into 240 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 15284.9
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 26, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 15284.92
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.

Moving on to step 9:
26 goes into 80 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 15284.923
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.

Step 10:
20 divided by 26 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15284.923
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.

Let's proceed to step 11:
26 can be fit into 200 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 15284.92307
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.

Advancing to step 12:
180 divided by 26 is 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 15284.923076
Subtracting 156 from 180 leaves us 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.

Advancing to step 13:
When dividing 240 by 26, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 15284.9230769
The remainder is 6 after subtracting 234 from 240.
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 14:
26 can be fit into 60 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 15284.92307692
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.

After the division, we end up with 15284.92307692 and a remainder of 8e-09.
