We look at the division of 42357547 by 342 
We want to divide 42357547 by 342.

Going ahead to step 1:
342 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 342

Let's proceed to step 2:
The number 342 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 342

Step 3:
342 goes into 423 1 times with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 342 away from 423, we end up with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 342

Going ahead to step 4:
If we divide 815 by 342, we get 2 and a remainder of 131.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 131 after subtracting 684 from 815.
Include the next digit (7) from the dividend after 131, then repeat: 1317 / 342

Moving on to step 5:
When dividing 1317 by 342, we get 3 with a remainder of 291.
The next digit of our result is 3. 
Result so far: 123.0
If we subtract 1026 from 1317, we get 291.
Grab the next digit (5) from the dividend, add it to 291, then carry on: 2915 / 342

Let's proceed to step 6:
If we divide 2915 by 342, we get 8 and a remainder of 179.
Write down 8 as next digit of the result. 
Result so far: 1238.0
If we take 2736 away from 2915, we end up with 179.
Grab the next digit (4) from the dividend, add it to 179, then carry on: 1794 / 342

On to step 7:
If we divide 1794 by 342, we get 5 and a remainder of 84.
The next digit of our result is 5. 
Result so far: 12385.0
The remainder is 84 after subtracting 1710 from 1794.
Include the next digit (7) from the dividend after 84, then repeat: 847 / 342

Advancing to step 8:
If we divide 847 by 342, we get 2 and a remainder of 163.
Write down 2 as next digit of the result. 
Result so far: 123852.0
If we subtract 684 from 847, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Let's proceed to step 9:
342 goes into 1630 4 times with a remainder of 262.
The next digit of our result is 4. 
Result so far: 123852.4
Deduct 1368 from 1630 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Moving on to step 10:
The number 342 fits into 2620 7 times, leaving a remainder of 226.
The number 7 becomes the next digit in our result. 
Result so far: 123852.47
Subtracting 2394 from 2620 leaves us with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 11:
The number 342 fits into 2260 6 times, leaving a remainder of 208.
Use 6 as the next digit of our solution. 
Result so far: 123852.476
Subtract 2052 from 2260 to get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 12:
2080 divided by 342 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 123852.4766
Subtracting 2052 from 2080 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 123852.4766, and the remainder is 0.00028.
