7830320 ÷ 343 
Our goal is to divide 7830320 by 343.

Step 1:
The number 343 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 343

Step 2:
78 divided by 343 is 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (3) from the dividend and append it to 78, then repeat: 783 / 343

Let's proceed to step 3:
783 divided by 343 is 2 with a remainder of 97.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 686 from 783 leaves us with 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 343

Advancing to step 4:
The number 343 fits into 970 2 times, leaving a remainder of 284.
Write down 2 as next digit of the result. 
Result so far: 22.0
Deduct 686 from 970 and we're left with 284.
Bring next digit (3) of the dividend behind the 284 and repeat the process: 2843 / 343

Moving on to step 5:
2843 divided by 343 is 8 with a remainder of 99.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Subtract 2744 from 2843 to get 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 343

Let's proceed to step 6:
The number 343 fits into 992 2 times, leaving a remainder of 306.
Write down 2 as next digit of the result. 
Result so far: 2282.0
If we take 686 away from 992, we end up with 306.
Take the next digit (0) from the dividend and append it to 306, then repeat: 3060 / 343

Moving on to step 7:
If we divide 3060 by 343, we get 8 and a remainder of 316.
The next digit of our result is 8. 
Result so far: 22828.0
Subtract 2744 from 3060 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.

On to step 8:
343 can be fit into 3160 9 times, resulting in a remainder of 73.
The number 9 becomes the next digit in our result. 
Result so far: 22828.9
If we take 3087 away from 3160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 9:
343 goes into 730 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 22828.92
If we subtract 686 from 730, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 10:
The number 343 fits into 440 1 times, leaving a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 22828.921
If we take 343 away from 440, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 11:
970 divided by 343 is 2 with a remainder of 284.
Put 2 as the next digit of the answer. 
Result so far: 22828.9212
The remainder is 284 after subtracting 686 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 12:
2840 divided by 343 is 8 with a remainder of 96.
The next digit of our result is 8. 
Result so far: 22828.92128
Subtract 2744 from 2840 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
343 goes into 960 2 times with a remainder of 274.
The number 2 becomes the next digit in our result. 
Result so far: 22828.921282
Subtract 686 from 960 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 14:
When dividing 2740 by 343, we get 7 with a remainder of 339.
The number 7 becomes the next digit in our result. 
Result so far: 22828.9212827
If we take 2401 away from 2740, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Let's proceed to step 15:
343 goes into 3390 9 times with a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 22828.92128279
The remainder is 303 after subtracting 3087 from 3390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final outcome is 22828.92128279, with a leftover of 3.03e-07.
