We look at the division of 818170 by 12 
We're looking to find how many times 12 goes into 818170.

Going ahead to step 1:
12 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 12

Advancing to step 2:
12 goes into 81 6 times with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 9 after subtracting 72 from 81.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 12

Going ahead to step 3:
If we divide 98 by 12, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 96 from 98 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Advancing to step 4:
The number 12 fits into 21 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 681.0
If we take 12 away from 21, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Let's proceed to step 5:
The number 12 fits into 97 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 6818.0
The remainder is 1 after subtracting 96 from 97.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 12

Let's proceed to step 6:
When dividing 10 by 12, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 68180.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 68180.8
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 8:
If we divide 40 by 12, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 68180.83
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 12 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 68180.833
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.

After the division, we end up with 68180.833 and a remainder of 0.0004.
