872863 divided by 12 
We want to divide 872863 by 12.

Moving on to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 12

Let's proceed to step 2:
When dividing 87 by 12, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 84 from 87 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 12

Going ahead to step 3:
12 goes into 32 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 72.0
Subtracting 24 from 32 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 12

Advancing to step 4:
The number 12 fits into 88 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 727.0
If we subtract 84 from 88, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 12

Step 5:
If we divide 46 by 12, we get 3 and a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 7273.0
If we take 36 away from 46, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

Advancing to step 6:
12 can be fit into 103 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 72738.0
Deduct 96 from 103 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 12, we get 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 72738.5
If we subtract 60 from 70, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 12 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 72738.58
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 72738.583
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 72738.5833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 72738.5833 with a balance of 4e-05.
