We look at the division of 306874 by 26 
The aim is to understand the frequency of 26 in 306874.

On to step 1:
The number 26 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 26

Step 2:
26 goes into 30 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 4 after subtracting 26 from 30.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 26

Advancing to step 3:
The number 26 fits into 46 1 times, leaving a remainder of 20.
The next digit of our result is 1. 
Result so far: 11.0
If we take 26 away from 46, we end up with 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 26

Advancing to step 4:
208 divided by 26 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 208 from 208 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 26

Let's proceed to step 5:
7 divided by 26 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1180.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 26

On to step 6:
The number 26 fits into 74 2 times, leaving a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 11802.0
The remainder is 22 after subtracting 52 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 11802.8
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.

Moving on to step 8:
The number 26 fits into 120 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11802.84
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 9:
When dividing 160 by 26, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 11802.846
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.

Going ahead to step 10:
26 goes into 40 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 11802.8461
If we subtract 26 from 40, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
26 goes into 140 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 11802.84615
If we subtract 130 from 140, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 26, we get 3 and a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 11802.846153
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 11802.8461538
If we take 208 away from 220, we end up 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 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: 11802.84615384
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.

Our division results in 11802.84615384 with a remaining 1.6e-08.
