We look at the division of 68186240 by 12 
We want to divide 68186240 by 12.

Going ahead to step 1:
If we divide 6 by 12, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 12

Let's proceed to step 2:
The number 12 fits into 68 5 times, leaving a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 8 after subtracting 60 from 68.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

Step 3:
81 divided by 12 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we subtract 72 from 81, we get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 12

On to step 4:
98 divided by 12 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 568.0
If we subtract 96 from 98, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

On to step 5:
When dividing 26 by 12, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 5682.0
If we subtract 24 from 26, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Advancing to step 6:
The number 12 fits into 22 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 56821.0
If we subtract 12 from 22, we get 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 12

Advancing to step 7:
104 divided by 12 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 568218.0
If we take 96 away from 104, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 12

Let's proceed to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 5682186.0
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.

Let's proceed to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 5682186.6
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.

Moving on to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 5682186.66
Subtract 72 from 80 to 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.

After the division, we end up with 5682186.66 and a remainder of 0.008.
