6 divided by 343 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 343

Let's proceed to step 2:
The number 343 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 343

Step 3:
The number 343 fits into 639 1 times, leaving a remainder of 296.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 296 after subtracting 343 from 639.
Bring next digit (0) of the dividend behind the 296 and repeat the process: 2960 / 343

Advancing to step 4:
The number 343 fits into 2960 8 times, leaving a remainder of 216.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 216 after subtracting 2744 from 2960.
Include the next digit (2) from the dividend after 216, then repeat: 2162 / 343

Moving on to step 5:
343 can be fit into 2162 6 times, resulting in a remainder of 104.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Subtract 2058 from 2162 to get 104.
Fetch the next digit (5) from the dividend, attach it to 104 and continue: 1045 / 343

Going ahead to step 6:
343 can be fit into 1045 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 1863.0
The remainder is 16 after subtracting 1029 from 1045.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 343

Step 7:
343 goes into 163 0 times with a remainder of 163.
Write down 0 as next digit of the result. 
Result so far: 18630.0
Subtracting 0 from 163 leaves us with 163.
Include the next digit (0) from the dividend after 163, then repeat: 1630 / 343

Advancing to step 8:
The number 343 fits into 1630 4 times, leaving a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 186304.0
Subtracting 1372 from 1630 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 9:
343 goes into 2580 7 times with a remainder of 179.
Record the quotient 7 as the next digit in the result. 
Result so far: 186304.7
Subtract 2401 from 2580 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Advancing to step 10:
343 can be fit into 1790 5 times, resulting in a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 186304.75
If we take 1715 away from 1790, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
343 goes into 750 2 times with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 186304.752
Deduct 686 from 750 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
The number 343 fits into 640 1 times, leaving a remainder of 297.
Record the quotient 1 as the next digit in the result. 
Result so far: 186304.7521
The remainder is 297 after subtracting 343 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 13:
When dividing 2970 by 343, we get 8 with a remainder of 226.
Write down 8 as next digit of the result. 
Result so far: 186304.75218
Subtracting 2744 from 2970 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Let's proceed to step 14:
343 goes into 2260 6 times with a remainder of 202.
Write down 6 as next digit of the result. 
Result so far: 186304.752186
Deduct 2058 from 2260 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 15:
The number 343 fits into 2020 5 times, leaving a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 186304.7521865
If we subtract 1715 from 2020, we get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

On to step 16:
If we divide 3050 by 343, we get 8 and a remainder of 306.
The next digit of our result is 8. 
Result so far: 186304.75218658
If we take 2744 away from 3050, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The quotient of the division is 186304.75218658, and the remainder is 3.06e-07.
