If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 343

Moving on to step 2:
If we divide 42 by 343, we get 0 and a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 343

Let's proceed to step 3:
343 goes into 424 1 times with a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 343 from 424 leaves us with 81.
Take the next digit (6) from the dividend and append it to 81, then repeat: 816 / 343

Moving on to step 4:
816 divided by 343 is 2 with a remainder of 130.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 686 from 816 leaves us with 130.
Append the next digit (8) from the dividend to 130 and continue with: 1308 / 343

Advancing to step 5:
343 goes into 1308 3 times with a remainder of 279.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
If we take 1029 away from 1308, we end up with 279.
Append the next digit (3) from the dividend to 279 and continue with: 2793 / 343

Moving on to step 6:
2793 divided by 343 is 8 with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 1238.0
Deduct 2744 from 2793 and we're left with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 343

On to step 7:
When dividing 499 by 343, we get 1 with a remainder of 156.
Use 1 as the next digit of our solution. 
Result so far: 12381.0
The remainder is 156 after subtracting 343 from 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

On to step 8:
When dividing 1560 by 343, we get 4 with a remainder of 188.
The number 4 becomes the next digit in our result. 
Result so far: 12381.4
Subtracting 1372 from 1560 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Going ahead to step 9:
343 goes into 1880 5 times with a remainder of 165.
Use 5 as the next digit of our solution. 
Result so far: 12381.45
Subtracting 1715 from 1880 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 10:
1650 divided by 343 is 4 with a remainder of 278.
The next digit of our result is 4. 
Result so far: 12381.454
If we subtract 1372 from 1650, we get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Advancing to step 11:
343 goes into 2780 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 12381.4548
The remainder is 36 after subtracting 2744 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 12:
When dividing 360 by 343, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 12381.45481
Subtract 343 from 360 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 13:
If we divide 170 by 343, we get 0 and a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 12381.45481
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
The number 343 fits into 1700 4 times, leaving a remainder of 328.
Put 4 as the next digit of the answer. 
Result so far: 12381.4548104
Deduct 1372 from 1700 and we're left with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 15:
When dividing 3280 by 343, we get 9 with a remainder of 193.
Record the quotient 9 as the next digit in the result. 
Result so far: 12381.45481049
Subtract 3087 from 3280 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

After the division, we end up with 12381.45481049 and a remainder of 1.93e-07.
