We look at the division of 42472425 by 343 
Let's see how many times 343 fits into 42472425.

Moving on to step 1:
343 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 343

Going ahead to step 2:
343 can be fit into 42 0 times, resulting in a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 343

On to step 3:
343 can be fit into 424 1 times, resulting in a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 343 away from 424, we end up with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 343

Step 4:
343 goes into 817 2 times with a remainder of 131.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 686 from 817 to get 131.
Fetch the next digit (2) from the dividend, attach it to 131 and continue: 1312 / 343

Moving on to step 5:
The number 343 fits into 1312 3 times, leaving a remainder of 283.
Put 3 as the next digit of the answer. 
Result so far: 123.0
The remainder is 283 after subtracting 1029 from 1312.
Append the next digit (4) from the dividend to 283 and continue with: 2834 / 343

Moving on to step 6:
2834 divided by 343 is 8 with a remainder of 90.
Use 8 as the next digit of our solution. 
Result so far: 1238.0
The remainder is 90 after subtracting 2744 from 2834.
Fetch the next digit (2) from the dividend, attach it to 90 and continue: 902 / 343

Advancing to step 7:
902 divided by 343 is 2 with a remainder of 216.
The number 2 becomes the next digit in our result. 
Result so far: 12382.0
Subtracting 686 from 902 leaves us with 216.
Fetch the next digit (5) from the dividend, attach it to 216 and continue: 2165 / 343

Step 8:
2165 divided by 343 is 6 with a remainder of 107.
The next digit of our result is 6. 
Result so far: 123826.0
If we take 2058 away from 2165, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Moving on to step 9:
343 can be fit into 1070 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 123826.3
The remainder is 41 after subtracting 1029 from 1070.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
343 goes into 410 1 times with a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 123826.31
Subtract 343 from 410 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 11:
670 divided by 343 is 1 with a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 123826.311
The remainder is 327 after subtracting 343 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

After the division, we end up with 123826.311 and a remainder of 0.0327.
