Let's divide 903733 by 28
The aim is to understand the frequency of 28 in 903733.

On to step 1:
When dividing 9 by 28, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 28

Going ahead to step 2:
90 divided by 28 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 84 from 90 and we're left with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 28

On to step 3:
63 divided by 28 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 56 from 63 to get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 28

On to step 4:
When dividing 77 by 28, we get 2 with a remainder of 21.
The next digit of our result is 2. 
Result so far: 322.0
If we subtract 56 from 77, we get 21.
Append the next digit (3) from the dividend to 21 and continue with: 213 / 28

Going ahead to step 5:
28 goes into 213 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 3227.0
Subtracting 196 from 213 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 28

Step 6:
The number 28 fits into 173 6 times, leaving a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 32276.0
If we subtract 168 from 173, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
50 divided by 28 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 32276.1
Subtract 28 from 50 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.

Going ahead to step 8:
220 divided by 28 is 7 with a remainder of 24.
Record the quotient 7 as the next digit in the result. 
Result so far: 32276.17
If we take 196 away from 220, 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.

On to step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 32276.178
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.

Going ahead to step 10:
28 goes into 160 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 32276.1785
Subtract 140 from 160 to 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 11:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 32276.17857
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.

Moving on to step 12:
40 divided by 28 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 32276.178571
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 13:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 32276.1785714
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.

Moving on to step 14:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 32276.17857142
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.

Our division results in 32276.17857142 with a remaining 2.4e-08.
