We're dividing 666003 by 26 
The aim is to understand the frequency of 26 in 666003.

Going ahead to step 1:
26 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 26

Let's proceed to step 2:
26 can be fit into 66 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 52 from 66 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 26

Advancing to step 3:
The number 26 fits into 146 5 times, leaving a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 130 from 146 to get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 26

Moving on to step 4:
If we divide 160 by 26, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 256.0
Subtract 156 from 160 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 26

Step 5:
If we divide 40 by 26, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 2561.0
If we subtract 26 from 40, we get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 26

Going ahead to step 6:
143 divided by 26 is 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 25615.0
Subtracting 130 from 143 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 26 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25615.5
Deduct 130 from 130 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 26 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25615.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 26, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25615.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 25615.5 with a balance of 0.0.
