We're dividing 861646 by 99 
Let's see how many times 99 fits into 861646.

Advancing to step 1:
99 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 99

Let's proceed to step 2:
99 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 99

Step 3:
861 divided by 99 is 8 with a remainder of 69.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 69 after subtracting 792 from 861.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 99

Going ahead to step 4:
696 divided by 99 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 693 from 696 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 99

Advancing to step 5:
99 goes into 34 0 times with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 870.0
If we take 0 away from 34, we end up with 34.
Take the next digit (6) from the dividend and append it to 34, then repeat: 346 / 99

Going ahead to step 6:
If we divide 346 by 99, we get 3 and a remainder of 49.
The next digit of our result is 3. 
Result so far: 8703.0
If we subtract 297 from 346, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
When dividing 490 by 99, we get 4 with a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 8703.4
Subtract 396 from 490 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 8:
When dividing 940 by 99, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 8703.49
If we subtract 891 from 940, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 99, we get 4 and a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 8703.494
If we subtract 396 from 490, we get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
If we divide 940 by 99, we get 9 and a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 8703.4949
Subtract 891 from 940 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
The number 99 fits into 490 4 times, leaving a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 8703.49494
Subtract 396 from 490 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 12:
The number 99 fits into 940 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 8703.494949
The remainder is 49 after subtracting 891 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 13:
99 goes into 490 4 times with a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 8703.4949494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 14:
When dividing 940 by 99, we get 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 8703.49494949
Deduct 891 from 940 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 8703.49494949 with a remainder of 4.9e-08.
