Let's divide 12192 by 28
Let's see how many times 28 fits into 12192.

Let's proceed to step 1:
1 divided by 28 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 28

Step 2:
28 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 28

Advancing to step 3:
If we divide 121 by 28, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 112 from 121 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 28

Advancing to step 4:
The number 28 fits into 99 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Deduct 84 from 99 and we're left with 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 28

Going ahead to step 5:
The number 28 fits into 152 5 times, leaving a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 435.0
If we take 140 away from 152, 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 6:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 435.4
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.

Advancing to step 7:
28 goes into 80 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 435.42
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.

Advancing to step 8:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 435.428
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.

On to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 435.4285
Subtract 140 from 160 to 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.

Step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 435.42857
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.

On to step 11:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 435.428571
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.

Advancing to step 12:
28 goes into 120 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 435.4285714
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.

On to step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 435.42857142
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.

Our division results in 435.42857142 with a remaining 2.4e-08.
