We look at the division of 393804 by 66 
Our goal is to divide 393804 by 66.

Step 1:
66 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 66

Step 2:
The number 66 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 66

Step 3:
393 divided by 66 is 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 330 from 393 leaves us with 63.
Grab the next digit (8) from the dividend, add it to 63, then carry on: 638 / 66

Going ahead to step 4:
638 divided by 66 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Deduct 594 from 638 and we're left with 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 66

Let's proceed to step 5:
66 can be fit into 440 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 596.0
The remainder is 44 after subtracting 396 from 440.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 66

Advancing to step 6:
444 divided by 66 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 5966.0
If we subtract 396 from 444, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 66 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 5966.7
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
When dividing 180 by 66, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 5966.72
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 9:
480 divided by 66 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 5966.727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
If we divide 180 by 66, we get 2 and a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 5966.7272
The remainder is 48 after subtracting 132 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
480 divided by 66 is 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 5966.72727
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 66 fits into 180 2 times, leaving a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 5966.727272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 13:
480 divided by 66 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 5966.7272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
66 can be fit into 180 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 5966.72727272
The remainder is 48 after subtracting 132 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 5966.72727272 and a remainder of 4.8e-08.
