We look at the division of 391833 by 66 
We're looking to find how many times 66 goes into 391833.

Let's proceed to step 1:
66 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
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:
66 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 66

Let's proceed to step 3:
The number 66 fits into 391 5 times, leaving a remainder of 61.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 61 after subtracting 330 from 391.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 66

On to step 4:
If we divide 618 by 66, we get 9 and a remainder of 24.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we take 594 away from 618, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 66

On to step 5:
When dividing 243 by 66, we get 3 with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 593.0
Subtract 198 from 243 to get 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 66

Advancing to step 6:
When dividing 453 by 66, we get 6 with a remainder of 57.
The next digit of our result is 6. 
Result so far: 5936.0
Subtract 396 from 453 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
When dividing 570 by 66, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 5936.8
The remainder is 42 after subtracting 528 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
66 goes into 420 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5936.86
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
The number 66 fits into 240 3 times, leaving a remainder of 42.
The next digit of our result is 3. 
Result so far: 5936.863
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
If we divide 420 by 66, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5936.8636
Deduct 396 from 420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 11:
66 goes into 240 3 times with a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 5936.86363
Deduct 198 from 240 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 12:
The number 66 fits into 420 6 times, leaving a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 5936.863636
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
66 can be fit into 240 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 5936.8636363
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
If we divide 420 by 66, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 5936.86363636
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 5936.86363636 with a remainder of 2.4e-08.
