We divide 664862 by 12
We want to figure out the number of times 664862 can be divided by 12.

Step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

On to step 2:
If we divide 66 by 12, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 60 away from 66, we end up with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 12

On to step 3:
The number 12 fits into 64 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtracting 60 from 64 leaves us with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 12

Step 4:
12 can be fit into 48 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 554.0
The remainder is 0 after subtracting 48 from 48.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 12

Step 5:
12 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 5540.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 12

Let's proceed to step 6:
62 divided by 12 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 55405.0
Deduct 60 from 62 and we're left 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.

Advancing to step 7:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 55405.1
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.

Advancing to step 8:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 55405.16
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.

Moving on to step 9:
80 divided by 12 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 55405.166
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.

The final result is 55405.166 with a remainder of 0.0008.
