Advancing to step 1:
The number 861 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 861

Going ahead to step 2:
If we divide 64 by 861, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 861

Let's proceed to step 3:
641 divided by 861 is 0 with a remainder of 641.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 641 and we're left with 641.
Include the next digit (2) from the dividend after 641, then repeat: 6412 / 861

On to step 4:
When dividing 6412 by 861, we get 7 with a remainder of 385.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6027 from 6412 to get 385.
Include the next digit (7) from the dividend after 385, then repeat: 3857 / 861

On to step 5:
861 can be fit into 3857 4 times, resulting in a remainder of 413.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
The remainder is 413 after subtracting 3444 from 3857.
Fetch the next digit (7) from the dividend, attach it to 413 and continue: 4137 / 861

Advancing to step 6:
861 can be fit into 4137 4 times, resulting in a remainder of 693.
The number 4 becomes the next digit in our result. 
Result so far: 744.0
Subtract 3444 from 4137 to get 693.
Include the next digit (1) from the dividend after 693, then repeat: 6931 / 861

On to step 7:
861 goes into 6931 8 times with a remainder of 43.
Write down 8 as next digit of the result. 
Result so far: 7448.0
Subtracting 6888 from 6931 leaves us with 43.
Fetch the next digit (6) from the dividend, attach it to 43 and continue: 436 / 861

Step 8:
861 goes into 436 0 times with a remainder of 436.
The number 0 becomes the next digit in our result. 
Result so far: 74480.0
If we subtract 0 from 436, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 9:
If we divide 4360 by 861, we get 5 and a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 74480.5
If we subtract 4305 from 4360, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 10:
861 can be fit into 550 0 times, resulting in a remainder of 550.
Write down 0 as next digit of the result. 
Result so far: 74480.5
The remainder is 550 after subtracting 0 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 11:
861 goes into 5500 6 times with a remainder of 334.
The number 6 becomes the next digit in our result. 
Result so far: 74480.506
Subtract 5166 from 5500 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 12:
861 goes into 3340 3 times with a remainder of 757.
The number 3 becomes the next digit in our result. 
Result so far: 74480.5063
Subtract 2583 from 3340 to get 757.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Step 13:
861 can be fit into 7570 8 times, resulting in a remainder of 682.
Write down 8 as next digit of the result. 
Result so far: 74480.50638
Subtracting 6888 from 7570 leaves us with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Going ahead to step 14:
861 can be fit into 6820 7 times, resulting in a remainder of 793.
Use 7 as the next digit of our solution. 
Result so far: 74480.506387
Subtracting 6027 from 6820 leaves us with 793.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7930, and continue the process.

Going ahead to step 15:
861 goes into 7930 9 times with a remainder of 181.
Record the quotient 9 as the next digit in the result. 
Result so far: 74480.5063879
Subtracting 7749 from 7930 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 16:
When dividing 1810 by 861, we get 2 with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 74480.50638792
The remainder is 88 after subtracting 1722 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final outcome is 74480.50638792, with a leftover of 8.8e-08.
