7683812 ÷ 399 
Let's see how many times 399 fits into 7683812.

Step 1:
The number 399 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 399

Advancing to step 2:
399 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 399

On to step 3:
399 goes into 768 1 times with a remainder of 369.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 399 from 768 to get 369.
Fetch the next digit (3) from the dividend, attach it to 369 and continue: 3693 / 399

Step 4:
3693 divided by 399 is 9 with a remainder of 102.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 102 after subtracting 3591 from 3693.
Take the next digit (8) from the dividend and append it to 102, then repeat: 1028 / 399

Step 5:
If we divide 1028 by 399, we get 2 and a remainder of 230.
The next digit of our result is 2. 
Result so far: 192.0
The remainder is 230 after subtracting 798 from 1028.
Include the next digit (1) from the dividend after 230, then repeat: 2301 / 399

Moving on to step 6:
2301 divided by 399 is 5 with a remainder of 306.
Put 5 as the next digit of the answer. 
Result so far: 1925.0
Deduct 1995 from 2301 and we're left with 306.
Take the next digit (2) from the dividend and append it to 306, then repeat: 3062 / 399

On to step 7:
399 can be fit into 3062 7 times, resulting in a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 19257.0
Subtract 2793 from 3062 to get 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Let's proceed to step 8:
The number 399 fits into 2690 6 times, leaving a remainder of 296.
Use 6 as the next digit of our solution. 
Result so far: 19257.6
Deduct 2394 from 2690 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
2960 divided by 399 is 7 with a remainder of 167.
Use 7 as the next digit of our solution. 
Result so far: 19257.67
If we take 2793 away from 2960, we end up with 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Let's proceed to step 10:
The number 399 fits into 1670 4 times, leaving a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 19257.674
If we take 1596 away from 1670, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
If we divide 740 by 399, we get 1 and a remainder of 341.
Use 1 as the next digit of our solution. 
Result so far: 19257.6741
Deduct 399 from 740 and we're left with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Let's proceed to step 12:
399 can be fit into 3410 8 times, resulting in a remainder of 218.
Use 8 as the next digit of our solution. 
Result so far: 19257.67418
Subtracting 3192 from 3410 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 13:
The number 399 fits into 2180 5 times, leaving a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 19257.674185
If we subtract 1995 from 2180, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Step 14:
399 goes into 1850 4 times with a remainder of 254.
Put 4 as the next digit of the answer. 
Result so far: 19257.6741854
Subtracting 1596 from 1850 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 15:
2540 divided by 399 is 6 with a remainder of 146.
Record the quotient 6 as the next digit in the result. 
Result so far: 19257.67418546
Deduct 2394 from 2540 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The final result is 19257.67418546 with a remainder of 1.46e-07.
