We look at the division of 3520771 by 343 
Let's see how many times 343 fits into 3520771.

Let's proceed to step 1:
3 divided by 343 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 343

Moving on to step 2:
When dividing 35 by 343, we get 0 with a remainder of 35.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 35, we get 35.
Take the next digit (2) from the dividend and append it to 35, then repeat: 352 / 343

Step 3:
343 can be fit into 352 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 343 from 352 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 343

Moving on to step 4:
If we divide 90 by 343, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 90 after subtracting 0 from 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 343

Let's proceed to step 5:
The number 343 fits into 907 2 times, leaving a remainder of 221.
The next digit of our result is 2. 
Result so far: 102.0
Deduct 686 from 907 and we're left with 221.
Grab the next digit (7) from the dividend, add it to 221, then carry on: 2217 / 343

Step 6:
If we divide 2217 by 343, we get 6 and a remainder of 159.
The number 6 becomes the next digit in our result. 
Result so far: 1026.0
The remainder is 159 after subtracting 2058 from 2217.
Bring next digit (1) of the dividend behind the 159 and repeat the process: 1591 / 343

Going ahead to step 7:
When dividing 1591 by 343, we get 4 with a remainder of 219.
The next digit of our result is 4. 
Result so far: 10264.0
Subtracting 1372 from 1591 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 8:
If we divide 2190 by 343, we get 6 and a remainder of 132.
Use 6 as the next digit of our solution. 
Result so far: 10264.6
The remainder is 132 after subtracting 2058 from 2190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 9:
343 goes into 1320 3 times with a remainder of 291.
Put 3 as the next digit of the answer. 
Result so far: 10264.63
Subtracting 1029 from 1320 leaves us with 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 10:
When dividing 2910 by 343, we get 8 with a remainder of 166.
Use 8 as the next digit of our solution. 
Result so far: 10264.638
If we subtract 2744 from 2910, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

On to step 11:
When dividing 1660 by 343, we get 4 with a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 10264.6384
The remainder is 288 after subtracting 1372 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
When dividing 2880 by 343, we get 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 10264.63848
The remainder is 136 after subtracting 2744 from 2880.
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 13:
1360 divided by 343 is 3 with a remainder of 331.
Record the quotient 3 as the next digit in the result. 
Result so far: 10264.638483
If we take 1029 away from 1360, we end up 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.

On to step 14:
If we divide 3310 by 343, we get 9 and a remainder of 223.
Put 9 as the next digit of the answer. 
Result so far: 10264.6384839
Deduct 3087 from 3310 and we're left 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.

Going ahead to step 15:
2230 divided by 343 is 6 with a remainder of 172.
The next digit of our result is 6. 
Result so far: 10264.63848396
If we take 2058 away from 2230, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

In conclusion, the division gives 10264.63848396 with a balance of 1.72e-07.
