We're dividing 6215092 by 399 
Our goal is to divide 6215092 by 399.

Step 1:
The number 399 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 399

Let's proceed to step 2:
The number 399 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 399

Advancing to step 3:
621 divided by 399 is 1 with a remainder of 222.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 399 away from 621, we end up with 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 399

Let's proceed to step 4:
The number 399 fits into 2225 5 times, leaving a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 1995 from 2225, we get 230.
Take the next digit (0) from the dividend and append it to 230, then repeat: 2300 / 399

On to step 5:
When dividing 2300 by 399, we get 5 with a remainder of 305.
Write down 5 as next digit of the result. 
Result so far: 155.0
Subtract 1995 from 2300 to get 305.
Include the next digit (9) from the dividend after 305, then repeat: 3059 / 399

Moving on to step 6:
399 goes into 3059 7 times with a remainder of 266.
Record the quotient 7 as the next digit in the result. 
Result so far: 1557.0
If we take 2793 away from 3059, we end up with 266.
Fetch the next digit (2) from the dividend, attach it to 266 and continue: 2662 / 399

Going ahead to step 7:
When dividing 2662 by 399, we get 6 with a remainder of 268.
The number 6 becomes the next digit in our result. 
Result so far: 15576.0
Subtracting 2394 from 2662 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Moving on to step 8:
2680 divided by 399 is 6 with a remainder of 286.
The number 6 becomes the next digit in our result. 
Result so far: 15576.6
If we subtract 2394 from 2680, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 9:
The number 399 fits into 2860 7 times, leaving a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 15576.67
Subtract 2793 from 2860 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 10:
670 divided by 399 is 1 with a remainder of 271.
Use 1 as the next digit of our solution. 
Result so far: 15576.671
Subtracting 399 from 670 leaves us with 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

Let's proceed to step 11:
When dividing 2710 by 399, we get 6 with a remainder of 316.
Use 6 as the next digit of our solution. 
Result so far: 15576.6716
Subtract 2394 from 2710 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 12:
If we divide 3160 by 399, we get 7 and a remainder of 367.
The number 7 becomes the next digit in our result. 
Result so far: 15576.67167
If we take 2793 away from 3160, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Advancing to step 13:
3670 divided by 399 is 9 with a remainder of 79.
The next digit of our result is 9. 
Result so far: 15576.671679
The remainder is 79 after subtracting 3591 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 14:
The number 399 fits into 790 1 times, leaving a remainder of 391.
Put 1 as the next digit of the answer. 
Result so far: 15576.6716791
Subtracting 399 from 790 leaves us with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 15:
If we divide 3910 by 399, we get 9 and a remainder of 319.
Record the quotient 9 as the next digit in the result. 
Result so far: 15576.67167919
The remainder is 319 after subtracting 3591 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

The quotient of the division is 15576.67167919, and the remainder is 3.19e-07.
