303708 divided by 28 
The aim is to understand the frequency of 28 in 303708.

Step 1:
If we divide 3 by 28, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
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

Advancing to step 2:
30 divided by 28 is 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 28 from 30 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 28

Let's proceed to step 3:
If we divide 23 by 28, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 23 and we're left with 23.
Append the next digit (7) from the dividend to 23 and continue with: 237 / 28

Let's proceed to step 4:
If we divide 237 by 28, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we subtract 224 from 237, we get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 28

Let's proceed to step 5:
28 goes into 130 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1084.0
If we take 112 away from 130, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 28

Advancing to step 6:
188 divided by 28 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 10846.0
If we subtract 168 from 188, 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.

Going ahead to step 7:
When dividing 200 by 28, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 10846.7
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.

Step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 10846.71
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.

Step 9:
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: 10846.714
If we take 112 away from 120, we end up 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.

Going ahead to step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 10846.7142
Subtracting 56 from 80 leaves us 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.

Let's proceed to step 11:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 10846.71428
Subtracting 224 from 240 leaves us 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.

Step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10846.714285
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.

On to step 13:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 10846.7142857
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.

Going ahead to step 14:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 10846.71428571
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.

In conclusion, the division gives 10846.71428571 with a balance of 1.2e-08.
