505663 divided by 26 
The aim is to understand the frequency of 26 in 505663.

Advancing to step 1:
When dividing 5 by 26, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 26

Step 2:
The number 26 fits into 50 1 times, leaving a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 26 from 50 to get 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 26

Step 3:
The number 26 fits into 245 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 11 after subtracting 234 from 245.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 26

Step 4:
The number 26 fits into 116 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 194.0
If we subtract 104 from 116, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 26

On to step 5:
The number 26 fits into 126 4 times, leaving a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 1944.0
Subtracting 104 from 126 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 26

Advancing to step 6:
26 can be fit into 223 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 19448.0
Subtracting 208 from 223 leaves us 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.

Step 7:
If we divide 150 by 26, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 19448.5
If we take 130 away from 150, 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 8:
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: 19448.57
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.

Step 9:
If we divide 180 by 26, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 19448.576
If we take 156 away from 180, we end up 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.

Step 10:
240 divided by 26 is 9 with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 19448.5769
The remainder is 6 after subtracting 234 from 240.
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 11:
26 can be fit into 60 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 19448.57692
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.

Let's proceed to step 12:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 19448.576923
Subtracting 78 from 80 leaves us 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.

On to step 13:
The number 26 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 19448.576923
The remainder is 20 after subtracting 0 from 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 14:
When dividing 200 by 26, we get 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 19448.57692307
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.

The quotient of the division is 19448.57692307, and the remainder is 1.8e-08.
