Let's divide 716991 by 26
The aim is to understand the frequency of 26 in 716991.

Advancing to step 1:
When dividing 7 by 26, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 26

Step 2:
26 goes into 71 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 19 after subtracting 52 from 71.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 26

On to step 3:
196 divided by 26 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 182 from 196 to get 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 26

Let's proceed to step 4:
149 divided by 26 is 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 275.0
If we take 130 away from 149, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 26

Step 5:
The number 26 fits into 199 7 times, leaving a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 2757.0
Subtract 182 from 199 to get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 26

Advancing to step 6:
If we divide 171 by 26, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 27576.0
Deduct 156 from 171 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
26 goes into 150 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 27576.5
The remainder is 20 after subtracting 130 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
26 goes into 200 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 27576.57
If we subtract 182 from 200, we 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 9:
26 goes into 180 6 times with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 27576.576
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.

Step 10:
When dividing 240 by 26, we get 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 27576.5769
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.

Advancing to step 11:
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: 27576.57692
If we subtract 52 from 60, we 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 12:
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: 27576.576923
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.

Moving on to step 13:
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: 27576.576923
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.

Advancing to step 14:
When dividing 200 by 26, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 27576.57692307
Subtracting 182 from 200 leaves us 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.

The final outcome is 27576.57692307, with a leftover of 1.8e-08.
