39140084 divided by 861 
We want to divide 39140084 by 861.

Going ahead to step 1:
When dividing 3 by 861, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 861

Step 2:
861 goes into 39 0 times with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (1) from the dividend to 39 and continue with: 391 / 861

Moving on to step 3:
When dividing 391 by 861, we get 0 with a remainder of 391.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 391 leaves us with 391.
Bring next digit (4) of the dividend behind the 391 and repeat the process: 3914 / 861

Going ahead to step 4:
861 goes into 3914 4 times with a remainder of 470.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 3444 from 3914 and we're left with 470.
Append the next digit (0) from the dividend to 470 and continue with: 4700 / 861

Moving on to step 5:
If we divide 4700 by 861, we get 5 and a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtract 4305 from 4700 to get 395.
Append the next digit (0) from the dividend to 395 and continue with: 3950 / 861

Moving on to step 6:
861 goes into 3950 4 times with a remainder of 506.
Put 4 as the next digit of the answer. 
Result so far: 454.0
If we subtract 3444 from 3950, we get 506.
Bring next digit (8) of the dividend behind the 506 and repeat the process: 5068 / 861

Let's proceed to step 7:
5068 divided by 861 is 5 with a remainder of 763.
Use 5 as the next digit of our solution. 
Result so far: 4545.0
Deduct 4305 from 5068 and we're left with 763.
Append the next digit (4) from the dividend to 763 and continue with: 7634 / 861

Advancing to step 8:
7634 divided by 861 is 8 with a remainder of 746.
Write down 8 as next digit of the result. 
Result so far: 45458.0
Subtracting 6888 from 7634 leaves us with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

Advancing to step 9:
When dividing 7460 by 861, we get 8 with a remainder of 572.
Use 8 as the next digit of our solution. 
Result so far: 45458.8
The remainder is 572 after subtracting 6888 from 7460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 10:
If we divide 5720 by 861, we get 6 and a remainder of 554.
Use 6 as the next digit of our solution. 
Result so far: 45458.86
Deduct 5166 from 5720 and we're left 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.

On to step 11:
861 can be fit into 5540 6 times, resulting in a remainder of 374.
Write down 6 as next digit of the result. 
Result so far: 45458.866
Subtract 5166 from 5540 to get 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

The final outcome is 45458.866, with a leftover of 0.0374.
