3792759 divided by 399 
Our goal is to divide 3792759 by 399.

On to step 1:
The number 399 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 399

Moving on to step 2:
When dividing 37 by 399, we get 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 399

Step 3:
The number 399 fits into 379 0 times, leaving a remainder of 379.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 379, we get 379.
Fetch the next digit (2) from the dividend, attach it to 379 and continue: 3792 / 399

Moving on to step 4:
When dividing 3792 by 399, we get 9 with a remainder of 201.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 3591 from 3792, we get 201.
Bring next digit (7) of the dividend behind the 201 and repeat the process: 2017 / 399

Going ahead to step 5:
2017 divided by 399 is 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 95.0
Deduct 1995 from 2017 and we're left with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 399

On to step 6:
225 divided by 399 is 0 with a remainder of 225.
The next digit of our result is 0. 
Result so far: 950.0
The remainder is 225 after subtracting 0 from 225.
Bring next digit (9) of the dividend behind the 225 and repeat the process: 2259 / 399

Advancing to step 7:
The number 399 fits into 2259 5 times, leaving a remainder of 264.
Record the quotient 5 as the next digit in the result. 
Result so far: 9505.0
If we take 1995 away from 2259, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 8:
399 goes into 2640 6 times with a remainder of 246.
The number 6 becomes the next digit in our result. 
Result so far: 9505.6
The remainder is 246 after subtracting 2394 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Going ahead to step 9:
When dividing 2460 by 399, we get 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 9505.66
If we subtract 2394 from 2460, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 9505.66 with a remainder of 0.066.
