Let's divide 664369 by 12
We want to divide 664369 by 12.

Step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

On to step 2:
When dividing 66 by 12, we get 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 66 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 12

On to step 3:
12 goes into 64 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 12

Let's proceed to step 4:
The number 12 fits into 43 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 553.0
Subtracting 36 from 43 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 12

Going ahead to step 5:
If we divide 76 by 12, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 5536.0
Deduct 72 from 76 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 12

Let's proceed to step 6:
12 goes into 49 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 55364.0
Subtracting 48 from 49 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 12, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 55364.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 55364.08
Subtracting 96 from 100 leaves us 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.

On to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 55364.083
If we subtract 36 from 40, 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.

On to step 10:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 55364.0833
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.

Our division results in 55364.0833 with a remaining 4e-05.
