We look at the division of 3092407 by 343 
Let's see how many times 343 fits into 3092407.

Step 1:
343 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 343

Let's proceed to step 2:
If we divide 30 by 343, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Grab the next digit (9) from the dividend, add it to 30, then carry on: 309 / 343

Let's proceed to step 3:
343 goes into 309 0 times with a remainder of 309.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Include the next digit (2) from the dividend after 309, then repeat: 3092 / 343

Step 4:
343 can be fit into 3092 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 5 after subtracting 3087 from 3092.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 343

On to step 5:
54 divided by 343 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we subtract 0 from 54, we get 54.
Include the next digit (0) from the dividend after 54, then repeat: 540 / 343

Step 6:
When dividing 540 by 343, we get 1 with a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 901.0
Subtracting 343 from 540 leaves us with 197.
Include the next digit (7) from the dividend after 197, then repeat: 1977 / 343

Advancing to step 7:
The number 343 fits into 1977 5 times, leaving a remainder of 262.
The next digit of our result is 5. 
Result so far: 9015.0
Subtract 1715 from 1977 to get 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 8:
343 can be fit into 2620 7 times, resulting in a remainder of 219.
Record the quotient 7 as the next digit in the result. 
Result so far: 9015.7
If we subtract 2401 from 2620, we get 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Moving on to step 9:
When dividing 2190 by 343, we get 6 with a remainder of 132.
Write down 6 as next digit of the result. 
Result so far: 9015.76
Subtracting 2058 from 2190 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
1320 divided by 343 is 3 with a remainder of 291.
Put 3 as the next digit of the answer. 
Result so far: 9015.763
Subtract 1029 from 1320 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Going ahead to step 11:
2910 divided by 343 is 8 with a remainder of 166.
The number 8 becomes the next digit in our result. 
Result so far: 9015.7638
If we take 2744 away from 2910, we end up with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Step 12:
When dividing 1660 by 343, we get 4 with a remainder of 288.
The next digit of our result is 4. 
Result so far: 9015.76384
Subtracting 1372 from 1660 leaves us with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 13:
The number 343 fits into 2880 8 times, leaving a remainder of 136.
The number 8 becomes the next digit in our result. 
Result so far: 9015.763848
If we take 2744 away from 2880, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 14:
343 goes into 1360 3 times with a remainder of 331.
Record the quotient 3 as the next digit in the result. 
Result so far: 9015.7638483
Subtracting 1029 from 1360 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Going ahead to step 15:
When dividing 3310 by 343, we get 9 with a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 9015.76384839
Subtracting 3087 from 3310 leaves us with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

After the division, we end up with 9015.76384839 and a remainder of 2.23e-07.
