The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 861

Moving on to step 2:
When dividing 39 by 861, we get 0 with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 861

On to step 3:
396 divided by 861 is 0 with a remainder of 396.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 396, we end up with 396.

Let's proceed to step 4:
861 can be fit into 3964 4 times, resulting in a remainder of 520.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 3444 from 3964, we get 520.
Append the next digit (1) from the dividend to 520 and continue with: 5201 / 861

Going ahead to step 5:
861 can be fit into 5201 6 times, resulting in a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 5166 away from 5201, we end up with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 861

Going ahead to step 6:
When dividing 357 by 861, we get 0 with a remainder of 357.
Put 0 as the next digit of the answer. 
Result so far: 460.0
If we subtract 0 from 357, we get 357.
Include the next digit (8) from the dividend after 357, then repeat: 3578 / 861

Going ahead to step 7:
3578 divided by 861 is 4 with a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 4604.0
The remainder is 134 after subtracting 3444 from 3578.
Include the next digit (2) from the dividend after 134, then repeat: 1342 / 861

Let's proceed to step 8:
1342 divided by 861 is 1 with a remainder of 481.
Record the quotient 1 as the next digit in the result. 
Result so far: 46041.0
Deduct 861 from 1342 and we're left with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 9:
The number 861 fits into 4810 5 times, leaving a remainder of 505.
The number 5 becomes the next digit in our result. 
Result so far: 46041.5
If we take 4305 away from 4810, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Moving on to step 10:
861 goes into 5050 5 times with a remainder of 745.
The number 5 becomes the next digit in our result. 
Result so far: 46041.55
Deduct 4305 from 5050 and we're left with 745.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7450, and continue the process.

Our division results in 46041.55 with a remaining 0.745.
