623291 divided by 26 
The aim is to understand the frequency of 26 in 623291.

Going ahead to step 1:
26 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 26

On to step 2:
The number 26 fits into 62 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 52 from 62 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 26

On to step 3:
103 divided by 26 is 3 with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 25 after subtracting 78 from 103.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 26

Step 4:
26 goes into 252 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 239.0
Subtract 234 from 252 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 26

On to step 5:
26 can be fit into 189 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 2397.0
Subtracting 182 from 189 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 26

Let's proceed to step 6:
When dividing 71 by 26, we get 2 with a remainder of 19.
The next digit of our result is 2. 
Result so far: 23972.0
If we subtract 52 from 71, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 26, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 23972.7
Subtract 182 from 190 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 8:
If we divide 80 by 26, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23972.73
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.

Moving on to step 9:
When dividing 20 by 26, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 23972.73
Subtracting 0 from 20 leaves us 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.

Step 10:
When dividing 200 by 26, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 23972.7307
Subtract 182 from 200 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
When dividing 180 by 26, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 23972.73076
Subtracting 156 from 180 leaves us 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.

Moving on to step 12:
240 divided by 26 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 23972.730769
Deduct 234 from 240 and we're left 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.

Going ahead to step 13:
If we divide 60 by 26, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 23972.7307692
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.

Advancing to step 14:
The number 26 fits into 80 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 23972.73076923
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.

The final result is 23972.73076923 with a remainder of 2e-09.
