309779 divided by 26 
The aim is to understand the frequency of 26 in 309779.

Moving on to step 1:
When dividing 3 by 26, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 26

Advancing to step 2:
30 divided by 26 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 26 away from 30, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 26

Let's proceed to step 3:
When dividing 49 by 26, we get 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 26 from 49 and we're left with 23.
Grab the next digit (7) from the dividend, add it to 23, then carry on: 237 / 26

Going ahead to step 4:
If we divide 237 by 26, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 119.0
If we take 234 away from 237, we end up with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 26

Let's proceed to step 5:
26 goes into 37 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1191.0
If we take 26 away from 37, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 26

Let's proceed to step 6:
26 goes into 119 4 times with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 11914.0
Subtracting 104 from 119 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 26, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 11914.5
Deduct 130 from 150 and we're left 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.

Moving on to step 8:
When dividing 200 by 26, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 11914.57
Deduct 182 from 200 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
180 divided by 26 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 11914.576
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
240 divided by 26 is 9 with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 11914.5769
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
26 goes into 60 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 11914.57692
If we subtract 52 from 60, we 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.

Going ahead to step 12:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 11914.576923
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.

Going ahead to step 13:
When dividing 20 by 26, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11914.576923
Deduct 0 from 20 and we're left 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 14:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 11914.57692307
The remainder is 18 after subtracting 182 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 11914.57692307, with a leftover of 1.8e-08.
