We're dividing 782508 by 28 
The aim is to understand the frequency of 28 in 782508.

Moving on to step 1:
28 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 28

Step 2:
28 goes into 78 2 times with a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 56 from 78 leaves us with 22.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 28

Moving on to step 3:
28 goes into 222 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 196 from 222, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 28

Going ahead to step 4:
The number 28 fits into 265 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 279.0
Subtracting 252 from 265 leaves us with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 28

Let's proceed to step 5:
130 divided by 28 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 2794.0
The remainder is 18 after subtracting 112 from 130.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 28

Advancing to step 6:
The number 28 fits into 188 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 27946.0
The remainder is 20 after subtracting 168 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
If we divide 200 by 28, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 27946.7
Subtracting 196 from 200 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.

Going ahead to step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 27946.71
Subtract 28 from 40 to 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.

Step 9:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 27946.714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 27946.7142
Subtracting 56 from 80 leaves us 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.

On to step 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 27946.71428
Subtract 224 from 240 to 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.

Moving on to step 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 27946.714285
If we take 140 away from 160, 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.

On to step 13:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 27946.7142857
The remainder is 4 after subtracting 196 from 200.
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 14:
If we divide 40 by 28, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 27946.71428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 27946.71428571, with a leftover of 1.2e-08.
