We're dividing 12979 by 28 
Let's see how many times 28 fits into 12979.

Moving on to step 1:
28 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 28

Moving on to step 2:
28 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 28

Moving on to step 3:
28 goes into 129 4 times with a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 112 from 129, we get 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 28

Advancing to step 4:
28 can be fit into 177 6 times, resulting in a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
The remainder is 9 after subtracting 168 from 177.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 28

Advancing to step 5:
The number 28 fits into 99 3 times, leaving a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 463.0
Deduct 84 from 99 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 6:
When dividing 150 by 28, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 463.5
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 28 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 463.53
Subtract 84 from 100 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.

Step 8:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 463.535
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.

On to step 9:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 463.5357
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 10:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 463.53571
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.

Going ahead to step 11:
The number 28 fits into 120 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 463.535714
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.

Advancing to step 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 463.5357142
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.

Going ahead to step 13:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 463.53571428
If we take 224 away from 240, we end up 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.

The final outcome is 463.53571428, with a leftover of 1.6e-08.
