We're dividing 28423 by 57 
Let's see how many times 57 fits into 28423.

Going ahead to step 1:
2 divided by 57 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 57

Moving on to step 2:
If we divide 28 by 57, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 57

On to step 3:
57 can be fit into 284 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 228 from 284, we get 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 57

Let's proceed to step 4:
If we divide 562 by 57, we get 9 and a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we subtract 513 from 562, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 57

Moving on to step 5:
If we divide 493 by 57, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 498.0
If we subtract 456 from 493, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 6:
57 can be fit into 370 6 times, resulting in a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 498.6
If we subtract 342 from 370, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 498.64
The remainder is 52 after subtracting 228 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
When dividing 520 by 57, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 498.649
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 57, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 498.6491
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
57 can be fit into 130 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 498.64912
If we subtract 114 from 130, we 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.

Advancing to step 11:
57 can be fit into 160 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 498.649122
The remainder is 46 after subtracting 114 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 498.649122, with a leftover of 4.6e-06.
