Let's divide 3827302 by 399
Our goal is to divide 3827302 by 399.

On to step 1:
399 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
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 399

On to step 2:
If we divide 38 by 399, we get 0 and a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 399

Step 3:
382 divided by 399 is 0 with a remainder of 382.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 382, we get 382.
Append the next digit (7) from the dividend to 382 and continue with: 3827 / 399

Let's proceed to step 4:
399 can be fit into 3827 9 times, resulting in a remainder of 236.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 236 after subtracting 3591 from 3827.
Bring next digit (3) of the dividend behind the 236 and repeat the process: 2363 / 399

Step 5:
The number 399 fits into 2363 5 times, leaving a remainder of 368.
Write down 5 as next digit of the result. 
Result so far: 95.0
The remainder is 368 after subtracting 1995 from 2363.
Fetch the next digit (0) from the dividend, attach it to 368 and continue: 3680 / 399

Going ahead to step 6:
The number 399 fits into 3680 9 times, leaving a remainder of 89.
The number 9 becomes the next digit in our result. 
Result so far: 959.0
Subtracting 3591 from 3680 leaves us with 89.
Grab the next digit (2) from the dividend, add it to 89, then carry on: 892 / 399

Let's proceed to step 7:
If we divide 892 by 399, we get 2 and a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 9592.0
Deduct 798 from 892 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 8:
If we divide 940 by 399, we get 2 and a remainder of 142.
The number 2 becomes the next digit in our result. 
Result so far: 9592.2
Subtract 798 from 940 to get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Advancing to step 9:
When dividing 1420 by 399, we get 3 with a remainder of 223.
The next digit of our result is 3. 
Result so far: 9592.23
Subtract 1197 from 1420 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 10:
When dividing 2230 by 399, we get 5 with a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 9592.235
The remainder is 235 after subtracting 1995 from 2230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 11:
399 goes into 2350 5 times with a remainder of 355.
The number 5 becomes the next digit in our result. 
Result so far: 9592.2355
Subtract 1995 from 2350 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

The final outcome is 9592.2355, with a leftover of 0.00355.
