We look at the division of 25395428 by 343 
We're looking to find how many times 343 goes into 25395428.

Going ahead to step 1:
343 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 343

Going ahead to step 2:
If we divide 25 by 343, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 343

Let's proceed to step 3:
343 goes into 253 0 times with a remainder of 253.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 253 after subtracting 0 from 253.
Grab the next digit (9) from the dividend, add it to 253, then carry on: 2539 / 343

Step 4:
When dividing 2539 by 343, we get 7 with a remainder of 138.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 138 after subtracting 2401 from 2539.
Bring next digit (5) of the dividend behind the 138 and repeat the process: 1385 / 343

Let's proceed to step 5:
When dividing 1385 by 343, we get 4 with a remainder of 13.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 1372 from 1385 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 343

Going ahead to step 6:
343 goes into 134 0 times with a remainder of 134.
Put 0 as the next digit of the answer. 
Result so far: 740.0
Subtracting 0 from 134 leaves us with 134.
Fetch the next digit (2) from the dividend, attach it to 134 and continue: 1342 / 343

Let's proceed to step 7:
343 goes into 1342 3 times with a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 7403.0
If we subtract 1029 from 1342, we get 313.
Append the next digit (8) from the dividend to 313 and continue with: 3138 / 343

Advancing to step 8:
3138 divided by 343 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 74039.0
Subtract 3087 from 3138 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
If we divide 510 by 343, we get 1 and a remainder of 167.
Put 1 as the next digit of the answer. 
Result so far: 74039.1
Subtract 343 from 510 to get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

Advancing to step 10:
1670 divided by 343 is 4 with a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 74039.14
If we take 1372 away from 1670, we end up with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 11:
343 goes into 2980 8 times with a remainder of 236.
The next digit of our result is 8. 
Result so far: 74039.148
Deduct 2744 from 2980 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 12:
When dividing 2360 by 343, we get 6 with a remainder of 302.
Record the quotient 6 as the next digit in the result. 
Result so far: 74039.1486
Subtracting 2058 from 2360 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Advancing to step 13:
343 goes into 3020 8 times with a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 74039.14868
If we subtract 2744 from 3020, we get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Moving on to step 14:
343 can be fit into 2760 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 74039.148688
Subtract 2744 from 2760 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 74039.148688, and the remainder is 1.6e-06.
