86865802 divided by 26 
The aim is to understand the frequency of 26 in 86865802.

Going ahead to step 1:
If we divide 8 by 26, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 26

Going ahead to step 2:
26 can be fit into 86 3 times, resulting in a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 78 away from 86, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 26

On to step 3:
The number 26 fits into 88 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 78 away from 88, we end up with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 26

Step 4:
106 divided by 26 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 334.0
The remainder is 2 after subtracting 104 from 106.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 26

Moving on to step 5:
When dividing 25 by 26, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 3340.0
If we take 0 away from 25, we end up with 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 26

Moving on to step 6:
When dividing 258 by 26, we get 9 with a remainder of 24.
The next digit of our result is 9. 
Result so far: 33409.0
Subtracting 234 from 258 leaves us with 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 26

Step 7:
26 goes into 240 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 334099.0
Subtract 234 from 240 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 26

On to step 8:
62 divided by 26 is 2 with a remainder of 10.
The next digit of our result is 2. 
Result so far: 3340992.0
If we take 52 away from 62, 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.

Moving on to step 9:
If we divide 100 by 26, we get 3 and a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3340992.3
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 10:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 3340992.38
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.

On to step 11:
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: 3340992.384
Subtracting 104 from 120 leaves us 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.

Let's proceed to step 12:
26 can be fit into 160 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 3340992.3846
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 13:
When dividing 40 by 26, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 3340992.38461
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.

Let's proceed to step 14:
26 goes into 140 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3340992.384615
Subtracting 130 from 140 leaves us 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.

Moving on to step 15:
When dividing 100 by 26, we get 3 with a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 3340992.3846153
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 16:
26 goes into 220 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 3340992.38461538
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.

Our division results in 3340992.38461538 with a remaining 1.2e-08.
