We're dividing 669100 by 26 
The aim is to understand the frequency of 26 in 669100.

Going ahead to step 1:
26 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 26

Moving on to step 2:
26 goes into 66 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 52 from 66 to get 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 26

Moving on to step 3:
149 divided by 26 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 130 from 149 and we're left with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 26

Advancing to step 4:
If we divide 191 by 26, we get 7 and a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtracting 182 from 191 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 26

Moving on to step 5:
26 can be fit into 90 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 2573.0
Subtract 78 from 90 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 26

Advancing to step 6:
26 can be fit into 120 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 25734.0
Subtract 104 from 120 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
160 divided by 26 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 25734.6
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.

On to step 8:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 25734.61
The remainder is 14 after subtracting 26 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
26 can be fit into 140 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25734.615
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.

Let's proceed to step 10:
If we divide 100 by 26, we get 3 and a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 25734.6153
Subtracting 78 from 100 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.

Step 11:
220 divided by 26 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 25734.61538
If we subtract 208 from 220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 12:
When dividing 120 by 26, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 25734.615384
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
When dividing 160 by 26, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 25734.6153846
If we subtract 156 from 160, we 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.

Step 14:
If we divide 40 by 26, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 25734.61538461
Subtracting 26 from 40 leaves us 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.

The final result is 25734.61538461 with a remainder of 1.4e-08.
