Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 858

On to step 2:
858 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 858

Moving on to step 3:
858 goes into 253 0 times with a remainder of 253.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 253 to get 253.

Step 4:
858 can be fit into 2537 2 times, resulting in a remainder of 821.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1716 from 2537, we get 821.
Append the next digit (0) from the dividend to 821 and continue with: 8210 / 858

Let's proceed to step 5:
When dividing 8210 by 858, we get 9 with a remainder of 488.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 7722 from 8210, we get 488.
Include the next digit (7) from the dividend after 488, then repeat: 4887 / 858

Step 6:
If we divide 4887 by 858, we get 5 and a remainder of 597.
Use 5 as the next digit of our solution. 
Result so far: 295.0
If we take 4290 away from 4887, we end up with 597.
Append the next digit (2) from the dividend to 597 and continue with: 5972 / 858

On to step 7:
5972 divided by 858 is 6 with a remainder of 824.
The next digit of our result is 6. 
Result so far: 2956.0
If we take 5148 away from 5972, we end up with 824.
Take the next digit (4) from the dividend and append it to 824, then repeat: 8244 / 858

Step 8:
The number 858 fits into 8244 9 times, leaving a remainder of 522.
Record the quotient 9 as the next digit in the result. 
Result so far: 29569.0
Deduct 7722 from 8244 and we're left with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 9:
858 can be fit into 5220 6 times, resulting in a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 29569.6
If we take 5148 away from 5220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
858 can be fit into 720 0 times, resulting in a remainder of 720.
Write down 0 as next digit of the result. 
Result so far: 29569.6
Subtracting 0 from 720 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Advancing to step 11:
858 goes into 7200 8 times with a remainder of 336.
Write down 8 as next digit of the result. 
Result so far: 29569.608
Subtracting 6864 from 7200 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 12:
When dividing 3360 by 858, we get 3 with a remainder of 786.
Use 3 as the next digit of our solution. 
Result so far: 29569.6083
If we subtract 2574 from 3360, we get 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

Going ahead to step 13:
When dividing 7860 by 858, we get 9 with a remainder of 138.
The next digit of our result is 9. 
Result so far: 29569.60839
Subtract 7722 from 7860 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 14:
1380 divided by 858 is 1 with a remainder of 522.
Record the quotient 1 as the next digit in the result. 
Result so far: 29569.608391
Subtracting 858 from 1380 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 15:
858 goes into 5220 6 times with a remainder of 72.
The next digit of our result is 6. 
Result so far: 29569.6083916
If we take 5148 away from 5220, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
The number 858 fits into 720 0 times, leaving a remainder of 720.
The next digit of our result is 0. 
Result so far: 29569.6083916
Subtract 0 from 720 to get 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

In conclusion, the division gives 29569.6083916 with a balance of 7.2e-07.
