We're dividing 863407 by 99 
Our goal is to divide 863407 by 99.

Moving on to step 1:
8 divided by 99 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 99

On to step 2:
If we divide 86 by 99, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 99

Let's proceed to step 3:
When dividing 863 by 99, we get 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 792 from 863 and we're left with 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 99

Step 4:
When dividing 714 by 99, we get 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 693 from 714, we get 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 99

On to step 5:
99 goes into 210 2 times with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 872.0
Subtracting 198 from 210 leaves us with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 99

Let's proceed to step 6:
If we divide 127 by 99, we get 1 and a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 8721.0
Deduct 99 from 127 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
When dividing 280 by 99, we get 2 with a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 8721.2
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 8:
99 goes into 820 8 times with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 8721.28
If we subtract 792 from 820, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
The number 99 fits into 280 2 times, leaving a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 8721.282
Subtracting 198 from 280 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 10:
99 can be fit into 820 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 8721.2828
Subtracting 792 from 820 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
If we divide 280 by 99, we get 2 and a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 8721.28282
Subtract 198 from 280 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 12:
When dividing 820 by 99, we get 8 with a remainder of 28.
The next digit of our result is 8. 
Result so far: 8721.282828
The remainder is 28 after subtracting 792 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 13:
280 divided by 99 is 2 with a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 8721.2828282
If we subtract 198 from 280, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 14:
When dividing 820 by 99, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 8721.28282828
Subtracting 792 from 820 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 8721.28282828, and the remainder is 2.8e-08.
