577541 divided by 26 
The aim is to understand the frequency of 26 in 577541.

Let's proceed to step 1:
When dividing 5 by 26, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 26

Advancing to step 2:
57 divided by 26 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 52 away from 57, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 26

Going ahead to step 3:
57 divided by 26 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 5 after subtracting 52 from 57.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 26

Advancing to step 4:
If we divide 55 by 26, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 222.0
Subtract 52 from 55 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 26

Let's proceed to step 5:
26 goes into 34 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 2221.0
Deduct 26 from 34 and we're left with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 26

Going ahead to step 6:
The number 26 fits into 81 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 22213.0
If we take 78 away from 81, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 26, we get 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 22213.1
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 22213.11
Deduct 26 from 40 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 22213.11 with a remaining 0.014.
