We look at the division of 396672 by 66 
Let's see how many times 66 fits into 396672.

Let's proceed to step 1:
66 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 66

Step 2:
39 divided by 66 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (6) from the dividend after 39, then repeat: 396 / 66

Step 3:
The number 66 fits into 396 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 396 from 396, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 66

Advancing to step 4:
66 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 66

Moving on to step 5:
If we divide 67 by 66, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 601.0
If we take 66 away from 67, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 66

Step 6:
12 divided by 66 is 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 6010.0
Subtracting 0 from 12 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 66, we get 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6010.1
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
66 goes into 540 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 6010.18
The remainder is 12 after subtracting 528 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
66 can be fit into 120 1 times, resulting in a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 6010.181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
66 goes into 540 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 6010.1818
Subtract 528 from 540 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
66 goes into 120 1 times with a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 6010.18181
Subtracting 66 from 120 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 12:
The number 66 fits into 540 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6010.181818
If we subtract 528 from 540, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 66, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 6010.1818181
If we subtract 66 from 120, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
66 can be fit into 540 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 6010.18181818
If we take 528 away from 540, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 6010.18181818, with a leftover of 1.2e-08.
