802437 divided by 28 
The aim is to understand the frequency of 28 in 802437.

Let's proceed to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 28

Step 2:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 56 from 80 to get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 28

Let's proceed to step 3:
The number 28 fits into 242 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 28.0
The remainder is 18 after subtracting 224 from 242.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 28

Let's proceed to step 4:
When dividing 184 by 28, we get 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 286.0
If we subtract 168 from 184, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 28

Step 5:
28 goes into 163 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 2865.0
If we subtract 140 from 163, we get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 28

Advancing to step 6:
The number 28 fits into 237 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 28658.0
The remainder is 13 after subtracting 224 from 237.
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:
When dividing 130 by 28, we get 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 28658.4
If we subtract 112 from 130, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
If we divide 180 by 28, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 28658.46
If we take 168 away from 180, 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.

Moving on to step 9:
If we divide 120 by 28, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 28658.464
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.

Step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 28658.4642
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 11:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 28658.46428
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:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 28658.464285
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.

Going ahead to step 13:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 28658.4642857
Subtract 196 from 200 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.

Step 14:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 28658.46428571
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.

Our division results in 28658.46428571 with a remaining 1.2e-08.
