572443 ÷ 26 
The aim is to understand the frequency of 26 in 572443.

Step 1:
26 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 26

Advancing to step 2:
26 goes into 57 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 52 from 57 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 26

Advancing to step 3:
The number 26 fits into 52 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 52 away from 52, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 26

Moving on to step 4:
4 divided by 26 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 220.0
Subtract 0 from 4 to get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 26

Step 5:
44 divided by 26 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 2201.0
Subtract 26 from 44 to get 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 26

Step 6:
When dividing 183 by 26, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 22017.0
Subtract 182 from 183 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 26, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22017.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 26 is 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 22017.03
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 26 fits into 220 8 times, leaving a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 22017.038
If we subtract 208 from 220, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
The number 26 fits into 120 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 22017.0384
Subtracting 104 from 120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
26 goes into 160 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 22017.03846
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 22017.038461
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.

Let's proceed to step 13:
If we divide 140 by 26, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 22017.0384615
Subtract 130 from 140 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
The number 26 fits into 100 3 times, leaving a remainder of 22.
The next digit of our result is 3. 
Result so far: 22017.03846153
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 22017.03846153 with a remainder of 2.2e-08.
