963391 ÷ 26 
The aim is to understand the frequency of 26 in 963391.

Let's proceed to step 1:
9 divided by 26 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 26

Step 2:
26 can be fit into 96 3 times, resulting in a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 78 away from 96, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 26

Moving on to step 3:
If we divide 183 by 26, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 182 from 183, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 26

Advancing to step 4:
26 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 370.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 26

On to step 5:
26 can be fit into 139 5 times, resulting in a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 3705.0
Subtract 130 from 139 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 26

Advancing to step 6:
26 can be fit into 91 3 times, resulting in a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 37053.0
If we take 78 away from 91, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
130 divided by 26 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 37053.5
Subtract 130 from 130 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.

Advancing to step 8:
0 divided by 26 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 37053.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
26 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 37053.5
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 final result is 37053.5 with a remainder of 0.0.
