We look at the division of 820378 by 26 
The aim is to understand the frequency of 26 in 820378.

Step 1:
26 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 26

Going ahead to step 2:
82 divided by 26 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we take 78 away from 82, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 26

Going ahead to step 3:
When dividing 40 by 26, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we take 26 away from 40, we end up with 14.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 26

Let's proceed to step 4:
143 divided by 26 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 315.0
If we subtract 130 from 143, we get 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 26

Going ahead to step 5:
The number 26 fits into 137 5 times, leaving a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 3155.0
The remainder is 7 after subtracting 130 from 137.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 26

Step 6:
26 goes into 78 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 31553.0
Subtracting 78 from 78 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
26 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31553.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
When dividing 0 by 26, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31553.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 31553.0, and the remainder is 0.0.
