We divide 128526 by 28
The aim is to understand the frequency of 28 in 128526.

Let's proceed to step 1:
The number 28 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 28

Let's proceed to step 2:
When dividing 12 by 28, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 28

Moving on to step 3:
When dividing 128 by 28, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 112 away from 128, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 28

Going ahead to step 4:
28 can be fit into 165 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 140 from 165 leaves us with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 28

On to step 5:
28 goes into 252 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 459.0
The remainder is 0 after subtracting 252 from 252.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 28

Going ahead to step 6:
If we divide 6 by 28, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 4590.0
If we take 0 away from 6, we end up 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.

Moving on to step 7:
60 divided by 28 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 4590.2
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 4590.21
If we take 28 away from 40, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4590.214
Deduct 112 from 120 and we're left 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 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 4590.2142
If we take 56 away from 80, 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 11:
240 divided by 28 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 4590.21428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 28, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4590.214285
Subtracting 140 from 160 leaves us 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.

Step 13:
200 divided by 28 is 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 4590.2142857
If we subtract 196 from 200, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 4590.21428571
Deduct 28 from 40 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 4590.21428571 and a remainder of 1.2e-08.
