865999 ÷ 99 
We want to divide 865999 by 99.

Advancing to step 1:
If we divide 8 by 99, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 99

Step 2:
When dividing 86 by 99, we get 0 with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Bring next digit (5) of the dividend behind the 86 and repeat the process: 865 / 99

Going ahead to step 3:
When dividing 865 by 99, we get 8 with a remainder of 73.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 792 from 865, we get 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 99

Moving on to step 4:
99 goes into 739 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
If we subtract 693 from 739, we get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 99

On to step 5:
99 can be fit into 469 4 times, resulting in a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 874.0
The remainder is 73 after subtracting 396 from 469.
Include the next digit (9) from the dividend after 73, then repeat: 739 / 99

Let's proceed to step 6:
The number 99 fits into 739 7 times, leaving a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 8747.0
Subtracting 693 from 739 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
The number 99 fits into 460 4 times, leaving a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 8747.4
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 8:
When dividing 640 by 99, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 8747.46
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
460 divided by 99 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8747.464
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
640 divided by 99 is 6 with a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 8747.4646
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
460 divided by 99 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8747.46464
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
99 goes into 640 6 times with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 8747.464646
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 13:
460 divided by 99 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 8747.4646464
The remainder is 64 after subtracting 396 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
The number 99 fits into 640 6 times, leaving a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 8747.46464646
Deduct 594 from 640 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 8747.46464646, and the remainder is 4.6e-08.
