We're dividing 304610 by 28 
The aim is to understand the frequency of 28 in 304610.

Going ahead to step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 28

Moving on to step 2:
The number 28 fits into 30 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 28 from 30.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 28

Advancing to step 3:
When dividing 24 by 28, we get 0 with a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (6) from the dividend, add it to 24, then carry on: 246 / 28

Advancing to step 4:
If we divide 246 by 28, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
If we take 224 away from 246, we end up with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 28

Advancing to step 5:
If we divide 221 by 28, we get 7 and a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 1087.0
If we subtract 196 from 221, we get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 28

Advancing to step 6:
When dividing 250 by 28, we get 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 10878.0
Subtract 224 from 250 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
28 can be fit into 260 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 10878.9
Subtracting 252 from 260 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.

Advancing to step 8:
28 goes into 80 2 times with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10878.92
Deduct 56 from 80 and we're left 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 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10878.928
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.

On to step 10:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10878.9285
The remainder is 20 after subtracting 140 from 160.
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 11:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 10878.92857
If we subtract 196 from 200, we 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.

Going ahead to step 12:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 10878.928571
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.

Step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 10878.9285714
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.

On to step 14:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 10878.92857142
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.

In conclusion, the division gives 10878.92857142 with a balance of 2.4e-08.
