68153261 ÷ 26 
The aim is to understand the frequency of 26 in 68153261.

Going ahead to step 1:
26 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 26

On to step 2:
68 divided by 26 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 52 from 68 to get 16.
Fetch the next digit (1) from the dividend, attach it to 16 and continue: 161 / 26

Let's proceed to step 3:
When dividing 161 by 26, we get 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 156 away from 161, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 26

Let's proceed to step 4:
When dividing 55 by 26, we get 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 262.0
The remainder is 3 after subtracting 52 from 55.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 26

On to step 5:
33 divided by 26 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 2621.0
Deduct 26 from 33 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 26

On to step 6:
If we divide 72 by 26, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 26212.0
If we take 52 away from 72, we end up with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 26

On to step 7:
If we divide 206 by 26, we get 7 and a remainder of 24.
The number 7 becomes the next digit in our result. 
Result so far: 262127.0
Deduct 182 from 206 and we're left with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 26

Advancing to step 8:
241 divided by 26 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2621279.0
Deduct 234 from 241 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
26 goes into 70 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2621279.2
The remainder is 18 after subtracting 52 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
26 goes into 180 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 2621279.26
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.

On to step 11:
26 goes into 240 9 times with a remainder of 6.
The next digit of our result is 9. 
Result so far: 2621279.269
If we subtract 234 from 240, we 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.

Moving on to step 12:
26 can be fit into 60 2 times, resulting in a remainder of 8.
The next digit of our result is 2. 
Result so far: 2621279.2692
Subtract 52 from 60 to 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.

Moving on to step 13:
26 can be fit into 80 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 2621279.26923
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
If we divide 20 by 26, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2621279.26923
If we take 0 away from 20, we end up 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 15:
26 goes into 200 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 2621279.2692307
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.

Advancing to step 16:
The number 26 fits into 180 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2621279.26923076
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 2621279.26923076 and a remainder of 2.4e-08.
