We look at the division of 14221 by 28 
Let's see how many times 28 fits into 14221.

Step 1:
1 divided by 28 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 28

Advancing to step 2:
If we divide 14 by 28, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 28

Going ahead to step 3:
28 can be fit into 142 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 5.0
If we take 140 away from 142, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 28

Let's proceed to step 4:
22 divided by 28 is 0 with a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 22 and we're left with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 28

Moving on 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: 507.0
If we subtract 196 from 221, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 6:
The number 28 fits into 250 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 507.8
If we take 224 away from 250, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
If we divide 260 by 28, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 507.89
The remainder is 8 after subtracting 252 from 260.
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:
When dividing 80 by 28, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 507.892
Subtract 56 from 80 to 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:
When dividing 240 by 28, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 507.8928
Deduct 224 from 240 and we're left 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.

Going ahead to step 10:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 507.89285
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 11:
28 can be fit into 200 7 times, resulting in a remainder of 4.
The next digit of our result is 7. 
Result so far: 507.892857
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.

Let's proceed to step 12:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 507.8928571
If we take 28 away from 40, 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 13:
If we divide 120 by 28, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 507.89285714
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.

Our division results in 507.89285714 with a remaining 8e-09.
