We look at the division of 28753429 by 343 
We want to figure out the number of times 28753429 can be divided by 343.

Going ahead to step 1:
If we divide 2 by 343, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 343

Advancing to step 2:
28 divided by 343 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 343

On to step 3:
343 goes into 287 0 times with a remainder of 287.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 287, we get 287.
Grab the next digit (5) from the dividend, add it to 287, then carry on: 2875 / 343

Let's proceed to step 4:
The number 343 fits into 2875 8 times, leaving a remainder of 131.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 2744 from 2875 leaves us with 131.
Grab the next digit (3) from the dividend, add it to 131, then carry on: 1313 / 343

Going ahead to step 5:
When dividing 1313 by 343, we get 3 with a remainder of 284.
Put 3 as the next digit of the answer. 
Result so far: 83.0
Subtracting 1029 from 1313 leaves us with 284.
Fetch the next digit (4) from the dividend, attach it to 284 and continue: 2844 / 343

Advancing to step 6:
343 can be fit into 2844 8 times, resulting in a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 838.0
If we subtract 2744 from 2844, we get 100.
Grab the next digit (2) from the dividend, add it to 100, then carry on: 1002 / 343

Moving on to step 7:
343 can be fit into 1002 2 times, resulting in a remainder of 316.
Use 2 as the next digit of our solution. 
Result so far: 8382.0
If we subtract 686 from 1002, we get 316.
Grab the next digit (9) from the dividend, add it to 316, then carry on: 3169 / 343

Advancing to step 8:
When dividing 3169 by 343, we get 9 with a remainder of 82.
The number 9 becomes the next digit in our result. 
Result so far: 83829.0
Subtracting 3087 from 3169 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
When dividing 820 by 343, we get 2 with a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 83829.2
Subtracting 686 from 820 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Advancing to step 10:
The number 343 fits into 1340 3 times, leaving a remainder of 311.
The next digit of our result is 3. 
Result so far: 83829.23
Deduct 1029 from 1340 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

On to step 11:
When dividing 3110 by 343, we get 9 with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 83829.239
The remainder is 23 after subtracting 3087 from 3110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
230 divided by 343 is 0 with a remainder of 230.
The next digit of our result is 0. 
Result so far: 83829.239
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 13:
The number 343 fits into 2300 6 times, leaving a remainder of 242.
Record the quotient 6 as the next digit in the result. 
Result so far: 83829.23906
Subtract 2058 from 2300 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

On to step 14:
2420 divided by 343 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 83829.239067
If we take 2401 away from 2420, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 15:
If we divide 190 by 343, we get 0 and a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 83829.239067
The remainder is 190 after subtracting 0 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 16:
When dividing 1900 by 343, we get 5 with a remainder of 185.
The next digit of our result is 5. 
Result so far: 83829.23906705
Subtract 1715 from 1900 to 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.

After the division, we end up with 83829.23906705 and a remainder of 1.85e-07.
