We're dividing 5715927 by 399 
Our goal is to divide 5715927 by 399.

Step 1:
399 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 399

Advancing to step 2:
The number 399 fits into 57 0 times, leaving a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 399

Step 3:
571 divided by 399 is 1 with a remainder of 172.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 399 from 571 leaves us with 172.
Fetch the next digit (5) from the dividend, attach it to 172 and continue: 1725 / 399

Let's proceed to step 4:
If we divide 1725 by 399, we get 4 and a remainder of 129.
The next digit of our result is 4. 
Result so far: 14.0
If we take 1596 away from 1725, we end up with 129.
Include the next digit (9) from the dividend after 129, then repeat: 1299 / 399

Step 5:
399 goes into 1299 3 times with a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 143.0
Subtracting 1197 from 1299 leaves us with 102.
Fetch the next digit (2) from the dividend, attach it to 102 and continue: 1022 / 399

Step 6:
If we divide 1022 by 399, we get 2 and a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 1432.0
Deduct 798 from 1022 and we're left with 224.
Take the next digit (7) from the dividend and append it to 224, then repeat: 2247 / 399

Going ahead to step 7:
The number 399 fits into 2247 5 times, leaving a remainder of 252.
Write down 5 as next digit of the result. 
Result so far: 14325.0
Subtract 1995 from 2247 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Let's proceed to step 8:
If we divide 2520 by 399, we get 6 and a remainder of 126.
Write down 6 as next digit of the result. 
Result so far: 14325.6
The remainder is 126 after subtracting 2394 from 2520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
The number 399 fits into 1260 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 14325.63
If we subtract 1197 from 1260, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 10:
399 can be fit into 630 1 times, resulting in a remainder of 231.
Use 1 as the next digit of our solution. 
Result so far: 14325.631
Subtracting 399 from 630 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Moving on to step 11:
When dividing 2310 by 399, we get 5 with a remainder of 315.
Put 5 as the next digit of the answer. 
Result so far: 14325.6315
The remainder is 315 after subtracting 1995 from 2310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 12:
If we divide 3150 by 399, we get 7 and a remainder of 357.
The next digit of our result is 7. 
Result so far: 14325.63157
Subtracting 2793 from 3150 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Let's proceed to step 13:
When dividing 3570 by 399, we get 8 with a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 14325.631578
Subtract 3192 from 3570 to get 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 14:
3780 divided by 399 is 9 with a remainder of 189.
The next digit of our result is 9. 
Result so far: 14325.6315789
The remainder is 189 after subtracting 3591 from 3780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 15:
When dividing 1890 by 399, we get 4 with a remainder of 294.
The number 4 becomes the next digit in our result. 
Result so far: 14325.63157894
If we take 1596 away from 1890, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Our division results in 14325.63157894 with a remaining 2.94e-07.
