We look at the division of 844806 by 28 
The aim is to understand the frequency of 28 in 844806.

Going ahead to step 1:
When dividing 8 by 28, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 28

Moving on to step 2:
28 can be fit into 84 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 84 away from 84, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 28

Going ahead to step 3:
If we divide 4 by 28, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 28

Step 4:
If we divide 48 by 28, we get 1 and a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 301.0
If we subtract 28 from 48, we get 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 28

Moving on to step 5:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3017.0
Subtract 196 from 200 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 28

Step 6:
The number 28 fits into 46 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 30171.0
Subtract 28 from 46 to 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.

Going ahead to step 7:
When dividing 180 by 28, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 30171.6
If we subtract 168 from 180, 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.

Let's proceed to step 8:
120 divided by 28 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 30171.64
The remainder is 8 after subtracting 112 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
The number 28 fits into 80 2 times, leaving a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 30171.642
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.

Moving on to step 10:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 30171.6428
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 11:
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: 30171.64285
Deduct 140 from 160 and we're left 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 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 30171.642857
If we take 196 away from 200, we end up 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 13:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 30171.6428571
Subtracting 28 from 40 leaves us 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.

On to step 14:
120 divided by 28 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 30171.64285714
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.

Our division results in 30171.64285714 with a remaining 8e-09.
