Let's divide 321284 by 28
The aim is to understand the frequency of 28 in 321284.

Step 1:
When dividing 3 by 28, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 28

Let's proceed to step 2:
32 divided by 28 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 28 from 32 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 28

Going ahead to step 3:
When dividing 41 by 28, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 11.0
Subtract 28 from 41 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 28

Step 4:
When dividing 132 by 28, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 114.0
Subtract 112 from 132 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 28

Let's proceed to step 5:
The number 28 fits into 208 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 1147.0
Subtracting 196 from 208 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 28

Going ahead to step 6:
If we divide 124 by 28, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 11474.0
If we take 112 away from 124, we end up 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 7:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11474.4
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.

Going ahead to step 8:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 11474.42
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.

Step 9:
If we divide 240 by 28, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 11474.428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 11474.4285
If we take 140 away from 160, we end up 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.

Moving on to step 11:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 11474.42857
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 12:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 11474.428571
Subtract 28 from 40 to 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.

Moving on to step 13:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11474.4285714
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.

Moving on to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 11474.42857142
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.

The final outcome is 11474.42857142, with a leftover of 2.4e-08.
