We look at the division of 25709411 by 343 
Let's see how many times 343 fits into 25709411.

Step 1:
343 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 343

Step 2:
If we divide 25 by 343, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Take the next digit (7) from the dividend and append it to 25, then repeat: 257 / 343

Going ahead to step 3:
When dividing 257 by 343, we get 0 with a remainder of 257.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Include the next digit (0) from the dividend after 257, then repeat: 2570 / 343

Let's proceed to step 4:
If we divide 2570 by 343, we get 7 and a remainder of 169.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 2401 from 2570 leaves us with 169.
Take the next digit (9) from the dividend and append it to 169, then repeat: 1699 / 343

Let's proceed to step 5:
The number 343 fits into 1699 4 times, leaving a remainder of 327.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 1372 away from 1699, we end up with 327.
Bring next digit (4) of the dividend behind the 327 and repeat the process: 3274 / 343

Moving on to step 6:
The number 343 fits into 3274 9 times, leaving a remainder of 187.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Deduct 3087 from 3274 and we're left with 187.
Grab the next digit (1) from the dividend, add it to 187, then carry on: 1871 / 343

Going ahead to step 7:
343 goes into 1871 5 times with a remainder of 156.
Use 5 as the next digit of our solution. 
Result so far: 7495.0
Subtracting 1715 from 1871 leaves us with 156.
Bring next digit (1) of the dividend behind the 156 and repeat the process: 1561 / 343

Step 8:
343 goes into 1561 4 times with a remainder of 189.
Write down 4 as next digit of the result. 
Result so far: 74954.0
The remainder is 189 after subtracting 1372 from 1561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Step 9:
The number 343 fits into 1890 5 times, leaving a remainder of 175.
The number 5 becomes the next digit in our result. 
Result so far: 74954.5
The remainder is 175 after subtracting 1715 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 10:
343 goes into 1750 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 74954.55
The remainder is 35 after subtracting 1715 from 1750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 74954.55 with a remaining 0.035.
