10855 divided by 12 
Our goal is to divide 10855 by 12.

Going ahead to step 1:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

Going ahead to step 2:
If we divide 10 by 12, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 12

Let's proceed to step 3:
When dividing 108 by 12, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 108 from 108, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 12

Advancing to step 4:
12 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 12

Advancing to step 5:
55 divided by 12 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 904.0
If we subtract 48 from 55, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 6:
The number 12 fits into 70 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 904.5
Subtract 60 from 70 to 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.

Advancing to step 7:
12 goes into 100 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 904.58
Deduct 96 from 100 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.

Going ahead to step 8:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 904.583
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.

On to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 904.5833
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.

The final outcome is 904.5833, with a leftover of 4e-05.
