We're dividing 666746 by 12 
We want to divide 666746 by 12.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Advancing to step 2:
The number 12 fits into 66 5 times, leaving a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 60 from 66 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Going ahead to step 3:
12 can be fit into 66 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 60 from 66 and we're left with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 12

On to step 4:
The number 12 fits into 67 5 times, leaving a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 555.0
Subtracting 60 from 67 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 12

On to step 5:
When dividing 74 by 12, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 5556.0
If we subtract 72 from 74, we get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

Step 6:
If we divide 26 by 12, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 55562.0
If we take 24 away from 26, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 55562.1
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.

Step 8:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 55562.16
If we subtract 72 from 80, 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.

Advancing to step 9:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 55562.166
Subtracting 72 from 80 leaves us 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 55562.166 with a remaining 0.0008.
