We're dividing 668066 by 26 
The aim is to understand the frequency of 26 in 668066.

Advancing to step 1:
26 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 26

Let's proceed to step 2:
66 divided by 26 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 52 from 66 to get 14.
Take the next digit (8) from the dividend and append it to 14, then repeat: 148 / 26

Let's proceed to step 3:
26 goes into 148 5 times with a remainder of 18.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 130 from 148, we get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 26

Going ahead to step 4:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 256.0
Subtract 156 from 180 to get 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 26

Let's proceed to step 5:
When dividing 246 by 26, we get 9 with a remainder of 12.
The next digit of our result is 9. 
Result so far: 2569.0
Subtract 234 from 246 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 26

On to step 6:
26 goes into 126 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 25694.0
Subtracting 104 from 126 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
26 can be fit into 220 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 25694.8
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
26 goes into 120 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 25694.84
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 26 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 25694.846
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
26 goes into 40 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 25694.8461
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
26 can be fit into 140 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 25694.84615
If we take 130 away from 140, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 26, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 25694.846153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 26, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 25694.8461538
The remainder is 12 after subtracting 208 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
If we divide 120 by 26, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 25694.84615384
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 25694.84615384 with a balance of 1.6e-08.
