Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 868

Moving on to step 2:
868 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (8) from the dividend to 39 and continue with: 398 / 868

Moving on to step 3:
868 goes into 398 0 times with a remainder of 398.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 398 and we're left with 398.
Include the next digit (0) from the dividend after 398, then repeat: 3980 / 868

Going ahead to step 4:
The number 868 fits into 3980 4 times, leaving a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 3472 from 3980 and we're left with 508.
Fetch the next digit (9) from the dividend, attach it to 508 and continue: 5089 / 868

Let's proceed to step 5:
When dividing 5089 by 868, we get 5 with a remainder of 749.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we subtract 4340 from 5089, we get 749.
Bring next digit (8) of the dividend behind the 749 and repeat the process: 7498 / 868

Advancing to step 6:
868 goes into 7498 8 times with a remainder of 554.
Record the quotient 8 as the next digit in the result. 
Result so far: 458.0
If we take 6944 away from 7498, we end up with 554.
Include the next digit (1) from the dividend after 554, then repeat: 5541 / 868

Step 7:
5541 divided by 868 is 6 with a remainder of 333.
Use 6 as the next digit of our solution. 
Result so far: 4586.0
Subtract 5208 from 5541 to get 333.
Append the next digit (5) from the dividend to 333 and continue with: 3335 / 868

Advancing to step 8:
The number 868 fits into 3335 3 times, leaving a remainder of 731.
Put 3 as the next digit of the answer. 
Result so far: 45863.0
Subtract 2604 from 3335 to get 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

On to step 9:
When dividing 7310 by 868, we get 8 with a remainder of 366.
The next digit of our result is 8. 
Result so far: 45863.8
Subtract 6944 from 7310 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 10:
3660 divided by 868 is 4 with a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 45863.84
Deduct 3472 from 3660 and we're left with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 11:
If we divide 1880 by 868, we get 2 and a remainder of 144.
Write down 2 as next digit of the result. 
Result so far: 45863.842
If we take 1736 away from 1880, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 12:
The number 868 fits into 1440 1 times, leaving a remainder of 572.
The number 1 becomes the next digit in our result. 
Result so far: 45863.8421
The remainder is 572 after subtracting 868 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 13:
The number 868 fits into 5720 6 times, leaving a remainder of 512.
Put 6 as the next digit of the answer. 
Result so far: 45863.84216
The remainder is 512 after subtracting 5208 from 5720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 14:
When dividing 5120 by 868, we get 5 with a remainder of 780.
The number 5 becomes the next digit in our result. 
Result so far: 45863.842165
If we subtract 4340 from 5120, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Advancing to step 15:
If we divide 7800 by 868, we get 8 and a remainder of 856.
Record the quotient 8 as the next digit in the result. 
Result so far: 45863.8421658
Subtracting 6944 from 7800 leaves us with 856.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8560, and continue the process.

Advancing to step 16:
If we divide 8560 by 868, we get 9 and a remainder of 748.
Put 9 as the next digit of the answer. 
Result so far: 45863.84216589
Subtract 7812 from 8560 to get 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

The final result is 45863.84216589 with a remainder of 7.48e-07.
