551662 divided by 26 
The aim is to understand the frequency of 26 in 551662.

Going ahead to step 1:
If we divide 5 by 26, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 26

Advancing to step 2:
If we divide 55 by 26, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 52 from 55 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 26

Step 3:
When dividing 31 by 26, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 26 from 31 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 26

Advancing to step 4:
When dividing 56 by 26, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 212.0
Deduct 52 from 56 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 26

On to step 5:
When dividing 46 by 26, we get 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 2121.0
Subtracting 26 from 46 leaves us with 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 26

Advancing to step 6:
26 can be fit into 202 7 times, resulting in a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 21217.0
Deduct 182 from 202 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 7:
26 goes into 200 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 21217.7
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.

Step 8:
If we divide 180 by 26, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 21217.76
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
The number 26 fits into 240 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 21217.769
Subtracting 234 from 240 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
26 goes into 60 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 21217.7692
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.

Step 11:
When dividing 80 by 26, we get 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 21217.76923
If we take 78 away from 80, we end up 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.

Step 12:
20 divided by 26 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 21217.76923
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.

On to step 13:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 21217.7692307
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.

Step 14:
When dividing 180 by 26, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 21217.76923076
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 21217.76923076, with a leftover of 2.4e-08.
