The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1716 from 2052 and we're left with 336.
Include the next digit (8) from the dividend after 336, then repeat: 3368 / 858

Let's proceed to step 5:
When dividing 3368 by 858, we get 3 with a remainder of 794.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 2574 from 3368, we get 794.
Append the next digit (0) from the dividend to 794 and continue with: 7940 / 858

On to step 6:
7940 divided by 858 is 9 with a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 239.0
Subtracting 7722 from 7940 leaves us with 218.
Include the next digit (4) from the dividend after 218, then repeat: 2184 / 858

Moving on to step 7:
When dividing 2184 by 858, we get 2 with a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 2392.0
Deduct 1716 from 2184 and we're left with 468.
Fetch the next digit (2) from the dividend, attach it to 468 and continue: 4682 / 858

Let's proceed to step 8:
4682 divided by 858 is 5 with a remainder of 392.
Use 5 as the next digit of our solution. 
Result so far: 23925.0
Subtract 4290 from 4682 to get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 9:
858 can be fit into 3920 4 times, resulting in a remainder of 488.
Put 4 as the next digit of the answer. 
Result so far: 23925.4
If we subtract 3432 from 3920, we get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 10:
If we divide 4880 by 858, we get 5 and a remainder of 590.
Use 5 as the next digit of our solution. 
Result so far: 23925.45
Deduct 4290 from 4880 and we're left with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Going ahead to step 11:
When dividing 5900 by 858, we get 6 with a remainder of 752.
Record the quotient 6 as the next digit in the result. 
Result so far: 23925.456
Subtracting 5148 from 5900 leaves us with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

On to step 12:
If we divide 7520 by 858, we get 8 and a remainder of 656.
Use 8 as the next digit of our solution. 
Result so far: 23925.4568
If we take 6864 away from 7520, we end up with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 13:
The number 858 fits into 6560 7 times, leaving a remainder of 554.
Use 7 as the next digit of our solution. 
Result so far: 23925.45687
Subtracting 6006 from 6560 leaves us with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Moving on to step 14:
5540 divided by 858 is 6 with a remainder of 392.
The next digit of our result is 6. 
Result so far: 23925.456876
Subtracting 5148 from 5540 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 15:
If we divide 3920 by 858, we get 4 and a remainder of 488.
Write down 4 as next digit of the result. 
Result so far: 23925.4568764
Subtracting 3432 from 3920 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 16:
858 goes into 4880 5 times with a remainder of 590.
The number 5 becomes the next digit in our result. 
Result so far: 23925.45687645
Subtract 4290 from 4880 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Our division results in 23925.45687645 with a remaining 5.9e-07.
