Step 1:
3 divided by 855 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 855

On to step 2:
39 divided by 855 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 855

On to step 3:
If we divide 393 by 855, we get 0 and a remainder of 393.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 393, we end up with 393.
Include the next digit (7) from the dividend after 393, then repeat: 3937 / 855

Moving on to step 4:
855 goes into 3937 4 times with a remainder of 517.
Put 4 as the next digit of the answer. 
Result so far: 4.0

Fetch the next digit (6) from the dividend, attach it to 517 and continue: 5176 / 855

On to step 5:
If we divide 5176 by 855, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 5130 from 5176, we get 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 855

Step 6:
When dividing 464 by 855, we get 0 with a remainder of 464.
The number 0 becomes the next digit in our result. 
Result so far: 460.0
Subtract 0 from 464 to get 464.
Fetch the next digit (7) from the dividend, attach it to 464 and continue: 4647 / 855

Step 7:
855 can be fit into 4647 5 times, resulting in a remainder of 372.
Write down 5 as next digit of the result. 
Result so far: 4605.0
Subtract 4275 from 4647 to get 372.
Fetch the next digit (9) from the dividend, attach it to 372 and continue: 3729 / 855

Moving on to step 8:
The number 855 fits into 3729 4 times, leaving a remainder of 309.
The next digit of our result is 4. 
Result so far: 46054.0
Deduct 3420 from 3729 and we're left with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Step 9:
The number 855 fits into 3090 3 times, leaving a remainder of 525.
The number 3 becomes the next digit in our result. 
Result so far: 46054.3
If we subtract 2565 from 3090, we get 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 10:
855 can be fit into 5250 6 times, resulting in a remainder of 120.
The next digit of our result is 6. 
Result so far: 46054.36
Deduct 5130 from 5250 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
855 can be fit into 1200 1 times, resulting in a remainder of 345.
The number 1 becomes the next digit in our result. 
Result so far: 46054.361
If we subtract 855 from 1200, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 12:
855 goes into 3450 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 46054.3614
Subtracting 3420 from 3450 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
When dividing 300 by 855, we get 0 with a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 46054.3614
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 14:
When dividing 3000 by 855, we get 3 with a remainder of 435.
Use 3 as the next digit of our solution. 
Result so far: 46054.361403
If we subtract 2565 from 3000, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Moving on to step 15:
855 goes into 4350 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 46054.3614035
If we subtract 4275 from 4350, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 16:
If we divide 750 by 855, we get 0 and a remainder of 750.
Use 0 as the next digit of our solution. 
Result so far: 46054.3614035
If we take 0 away from 750, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Our division results in 46054.3614035 with a remaining 7.5e-07.
