Let's divide 306840 by 26
The aim is to understand the frequency of 26 in 306840.

Step 1:
The number 26 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 26

Advancing to step 2:
When dividing 30 by 26, we get 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.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 26

Advancing to step 3:
46 divided by 26 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
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

Let's proceed to step 4:
26 goes into 208 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 118.0
If we take 208 away from 208, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 26

Moving on to step 5:
When dividing 4 by 26, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 1180.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 26

Going ahead to step 6:
40 divided by 26 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11801.0
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.

Step 7:
The number 26 fits into 140 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 11801.5
The remainder is 10 after subtracting 130 from 140.
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 8:
100 divided by 26 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 11801.53
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.

Going ahead to step 9:
The number 26 fits into 220 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 11801.538
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 10:
When dividing 120 by 26, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 11801.5384
The remainder is 16 after subtracting 104 from 120.
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 11:
26 can be fit into 160 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 11801.53846
The remainder is 4 after subtracting 156 from 160.
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 12:
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: 11801.538461
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 13:
The number 26 fits into 140 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 11801.5384615
Subtract 130 from 140 to 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.

Moving on to step 14:
If we divide 100 by 26, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 11801.53846153
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.

The final result is 11801.53846153 with a remainder of 2.2e-08.
