42594104 ÷ 343 
Let's see how many times 343 fits into 42594104.

Going ahead to step 1:
343 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 343

Going ahead to step 2:
If we divide 42 by 343, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 343

Going ahead to step 3:
425 divided by 343 is 1 with a remainder of 82.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 343 from 425 to get 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 343

On to step 4:
The number 343 fits into 829 2 times, leaving a remainder of 143.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 686 from 829 leaves us with 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 343

On to step 5:
The number 343 fits into 1434 4 times, leaving a remainder of 62.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 1372 from 1434 to get 62.
Append the next digit (1) from the dividend to 62 and continue with: 621 / 343

Step 6:
621 divided by 343 is 1 with a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 1241.0
Deduct 343 from 621 and we're left with 278.
Bring next digit (0) of the dividend behind the 278 and repeat the process: 2780 / 343

On to step 7:
2780 divided by 343 is 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 12418.0
The remainder is 36 after subtracting 2744 from 2780.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 343

Step 8:
The number 343 fits into 364 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 124181.0
If we take 343 away from 364, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
343 can be fit into 210 0 times, resulting in a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 124181.0
If we subtract 0 from 210, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
When dividing 2100 by 343, we get 6 with a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 124181.06
Subtract 2058 from 2100 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
343 goes into 420 1 times with a remainder of 77.
The next digit of our result is 1. 
Result so far: 124181.061
The remainder is 77 after subtracting 343 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 12:
343 goes into 770 2 times with a remainder of 84.
Put 2 as the next digit of the answer. 
Result so far: 124181.0612
Subtract 686 from 770 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 13:
343 can be fit into 840 2 times, resulting in a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 124181.06122
If we take 686 away from 840, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The quotient of the division is 124181.06122, and the remainder is 0.000154.
