Let's divide 862852 by 12
We want to divide 862852 by 12.

Step 1:
If we divide 8 by 12, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 12

On to step 2:
If we divide 86 by 12, we get 7 and a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 2 after subtracting 84 from 86.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 12

Let's proceed to step 3:
If we divide 22 by 12, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we subtract 12 from 22, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Step 4:
12 can be fit into 108 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 719.0
If we take 108 away from 108, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 12

Step 5:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 7190.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 12

Step 6:
12 goes into 52 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 71904.0
If we take 48 away from 52, 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.

Moving on to step 7:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 71904.3
Subtract 36 from 40 to 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.

Moving on to step 8:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 71904.33
Deduct 36 from 40 and we're left 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.

The final result is 71904.33 with a remainder of 0.004.
