Let's divide 871103 by 12
Our goal is to divide 871103 by 12.

Advancing to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 12

On to step 2:
12 goes into 87 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 84 from 87 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 12

Moving on to step 3:
12 goes into 31 2 times with a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 72.0
Subtracting 24 from 31 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 12

Moving on to step 4:
The number 12 fits into 71 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 725.0
Subtract 60 from 71 to get 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Advancing to step 5:
110 divided by 12 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 7259.0
Deduct 108 from 110 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 12

On to step 6:
When dividing 23 by 12, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 72591.0
If we subtract 12 from 23, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 72591.9
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 72591.91
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 72591.916
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 72591.9166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 72591.9166 with a remaining 8e-05.
