We're dividing 250664 by 26 
The aim is to understand the frequency of 26 in 250664.

Advancing to step 1:
26 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 26

Going ahead to step 2:
When dividing 25 by 26, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 26

On to step 3:
250 divided by 26 is 9 with a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 234 from 250, we get 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 26

Advancing to step 4:
26 goes into 166 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 96.0
Deduct 156 from 166 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 26

Let's proceed to step 5:
When dividing 106 by 26, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 964.0
If we take 104 away from 106, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 26

Advancing to step 6:
26 can be fit into 24 0 times, resulting in a remainder of 24.
Write down 0 as next digit of the result. 
Result so far: 9640.0
Deduct 0 from 24 and we're left 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 7:
The number 26 fits into 240 9 times, leaving a remainder of 6.
The next digit of our result is 9. 
Result so far: 9640.9
If we take 234 away from 240, we end up 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 8:
If we divide 60 by 26, we get 2 and a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 9640.92
The remainder is 8 after subtracting 52 from 60.
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 9:
26 goes into 80 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 9640.923
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
The number 26 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9640.923
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 11:
26 can be fit into 200 7 times, resulting in a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 9640.92307
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.

Moving on to step 12:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 9640.923076
Subtract 156 from 180 to 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.

Advancing to step 13:
26 goes into 240 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 9640.9230769
If we take 234 away from 240, we end up 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.

On to step 14:
26 goes into 60 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 9640.92307692
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 9640.92307692 with a remainder of 8e-09.
