We're dividing 807052 by 28 
The aim is to understand the frequency of 28 in 807052.

Advancing to step 1:
8 divided by 28 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 28

On to step 2:
80 divided by 28 is 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 24 after subtracting 56 from 80.
Fetch the next digit (7) from the dividend, attach it to 24 and continue: 247 / 28

Moving on to step 3:
28 can be fit into 247 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 224 from 247 and we're left with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 28

Step 4:
The number 28 fits into 230 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 288.0
If we take 224 away from 230, we end up with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 28

Step 5:
28 goes into 65 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2882.0
Subtracting 56 from 65 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 28

Moving on to step 6:
When dividing 92 by 28, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 28823.0
Subtract 84 from 92 to 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.

Step 7:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 28823.2
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 28823.28
If we take 224 away from 240, we end up 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 9:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 28823.285
If we subtract 140 from 160, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 28823.2857
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.

Moving on to step 11:
40 divided by 28 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 28823.28571
If we subtract 28 from 40, 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.

On to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 28823.285714
Subtracting 112 from 120 leaves us 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 13:
When dividing 80 by 28, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 28823.2857142
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.

Advancing to step 14:
28 goes into 240 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28823.28571428
If we take 224 away from 240, we end up 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.

After the division, we end up with 28823.28571428 and a remainder of 1.6e-08.
