We're dividing 662553 by 26 
The aim is to understand the frequency of 26 in 662553.

On to step 1:
26 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 26

Moving on to step 2:
66 divided by 26 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 52 from 66, we get 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 26

On to step 3:
26 goes into 142 5 times with a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 130 from 142, we get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 26

Advancing to step 4:
125 divided by 26 is 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
The remainder is 21 after subtracting 104 from 125.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 26

Step 5:
If we divide 215 by 26, we get 8 and a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 2548.0
If we take 208 away from 215, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 26

Moving on to step 6:
The number 26 fits into 73 2 times, leaving a remainder of 21.
The next digit of our result is 2. 
Result so far: 25482.0
The remainder is 21 after subtracting 52 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
When dividing 210 by 26, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 25482.8
Deduct 208 from 210 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.

Going ahead to step 8:
20 divided by 26 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 25482.8
Subtract 0 from 20 to get 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 9:
If we divide 200 by 26, we get 7 and a remainder of 18.
The next digit of our result is 7. 
Result so far: 25482.807
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.

On to step 10:
180 divided by 26 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 25482.8076
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.

Step 11:
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: 25482.80769
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.

Let's proceed to step 12:
26 can be fit into 60 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 25482.807692
Subtracting 52 from 60 leaves us 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.

Moving on to step 13:
If we divide 80 by 26, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 25482.8076923
If we subtract 78 from 80, we 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.

Let's proceed to step 14:
The number 26 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 25482.8076923
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 25482.8076923 and a remainder of 2e-08.
