Let's divide 392091 by 66
We want to figure out the number of times 392091 can be divided by 66.

Let's proceed to step 1:
If we divide 3 by 66, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 66

Going ahead to step 2:
66 goes into 39 0 times with a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 66

Advancing to step 3:
If we divide 392 by 66, we get 5 and a remainder of 62.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 62 after subtracting 330 from 392.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 66

Moving on to step 4:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
If we subtract 594 from 620, we get 26.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 66

Step 5:
When dividing 269 by 66, we get 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 594.0
The remainder is 5 after subtracting 264 from 269.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 66

On to step 6:
The number 66 fits into 51 0 times, leaving a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 5940.0
If we subtract 0 from 51, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 7:
66 goes into 510 7 times with a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 5940.7
If we subtract 462 from 510, 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 8:
The number 66 fits into 480 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 5940.77
Deduct 462 from 480 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 5940.77 and a remainder of 0.018.
