We look at the division of 2925803 by 399 
We're looking to find how many times 399 goes into 2925803.

Step 1:
When dividing 2 by 399, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 399

Let's proceed to step 2:
If we divide 29 by 399, we get 0 and a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 29 after subtracting 0 from 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 399

Moving on to step 3:
399 can be fit into 292 0 times, resulting in a remainder of 292.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 292 leaves us with 292.
Take the next digit (5) from the dividend and append it to 292, then repeat: 2925 / 399

On to step 4:
399 can be fit into 2925 7 times, resulting in a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 2793 from 2925 to get 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 399

On to step 5:
399 goes into 1328 3 times with a remainder of 131.
Record the quotient 3 as the next digit in the result. 
Result so far: 73.0
The remainder is 131 after subtracting 1197 from 1328.
Take the next digit (0) from the dividend and append it to 131, then repeat: 1310 / 399

Step 6:
1310 divided by 399 is 3 with a remainder of 113.
The next digit of our result is 3. 
Result so far: 733.0
If we take 1197 away from 1310, we end up with 113.
Include the next digit (3) from the dividend after 113, then repeat: 1133 / 399

Moving on to step 7:
1133 divided by 399 is 2 with a remainder of 335.
Put 2 as the next digit of the answer. 
Result so far: 7332.0
If we subtract 798 from 1133, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Step 8:
399 goes into 3350 8 times with a remainder of 158.
Write down 8 as next digit of the result. 
Result so far: 7332.8
If we subtract 3192 from 3350, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
399 can be fit into 1580 3 times, resulting in a remainder of 383.
Write down 3 as next digit of the result. 
Result so far: 7332.83
If we take 1197 away from 1580, we end up with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Moving on to step 10:
399 goes into 3830 9 times with a remainder of 239.
The next digit of our result is 9. 
Result so far: 7332.839
Deduct 3591 from 3830 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 11:
399 can be fit into 2390 5 times, resulting in a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 7332.8395
The remainder is 395 after subtracting 1995 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 12:
399 goes into 3950 9 times with a remainder of 359.
The number 9 becomes the next digit in our result. 
Result so far: 7332.83959
Deduct 3591 from 3950 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 13:
399 can be fit into 3590 8 times, resulting in a remainder of 398.
The next digit of our result is 8. 
Result so far: 7332.839598
If we subtract 3192 from 3590, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

On to step 14:
399 goes into 3980 9 times with a remainder of 389.
Put 9 as the next digit of the answer. 
Result so far: 7332.8395989
If we subtract 3591 from 3980, we get 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 15:
If we divide 3890 by 399, we get 9 and a remainder of 299.
The number 9 becomes the next digit in our result. 
Result so far: 7332.83959899
If we subtract 3591 from 3890, we get 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

The final result is 7332.83959899 with a remainder of 2.99e-07.
