We're dividing 28172251 by 979 
Let's see how many times 979 fits into 28172251.

Step 1:
979 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 979

On to step 2:
979 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 979

On to step 3:
979 can be fit into 281 0 times, resulting in a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 281 and we're left with 281.
Take the next digit (7) from the dividend and append it to 281, then repeat: 2817 / 979

Going ahead to step 4:
When dividing 2817 by 979, we get 2 with a remainder of 859.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 859 after subtracting 1958 from 2817.
Append the next digit (2) from the dividend to 859 and continue with: 8592 / 979

Let's proceed to step 5:
If we divide 8592 by 979, we get 8 and a remainder of 760.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 7832 from 8592 leaves us with 760.
Grab the next digit (2) from the dividend, add it to 760, then carry on: 7602 / 979

Let's proceed to step 6:
979 goes into 7602 7 times with a remainder of 749.
The next digit of our result is 7. 
Result so far: 287.0
The remainder is 749 after subtracting 6853 from 7602.
Bring next digit (5) of the dividend behind the 749 and repeat the process: 7495 / 979

Let's proceed to step 7:
If we divide 7495 by 979, we get 7 and a remainder of 642.
Record the quotient 7 as the next digit in the result. 
Result so far: 2877.0
If we subtract 6853 from 7495, we get 642.
Append the next digit (1) from the dividend to 642 and continue with: 6421 / 979

Let's proceed to step 8:
When dividing 6421 by 979, we get 6 with a remainder of 547.
The number 6 becomes the next digit in our result. 
Result so far: 28776.0
Subtract 5874 from 6421 to get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Step 9:
5470 divided by 979 is 5 with a remainder of 575.
Record the quotient 5 as the next digit in the result. 
Result so far: 28776.5
Subtract 4895 from 5470 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 10:
979 can be fit into 5750 5 times, resulting in a remainder of 855.
Write down 5 as next digit of the result. 
Result so far: 28776.55
Subtracting 4895 from 5750 leaves us with 855.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8550, and continue the process.

The final outcome is 28776.55, with a leftover of 0.855.
