Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 342

Moving on to step 2:
The number 342 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 342

Step 3:
432 divided by 342 is 1 with a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 1.0

Moving on to step 4:
342 goes into 907 2 times with a remainder of 223.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 684 from 907, we get 223.
Take the next digit (8) from the dividend and append it to 223, then repeat: 2238 / 342

Going ahead to step 5:
2238 divided by 342 is 6 with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 126.0
Deduct 2052 from 2238 and we're left with 186.
Take the next digit (7) from the dividend and append it to 186, then repeat: 1867 / 342

Advancing to step 6:
The number 342 fits into 1867 5 times, leaving a remainder of 157.
The next digit of our result is 5. 
Result so far: 1265.0
If we take 1710 away from 1867, we end up with 157.
Append the next digit (7) from the dividend to 157 and continue with: 1577 / 342

Let's proceed to step 7:
When dividing 1577 by 342, we get 4 with a remainder of 209.
Put 4 as the next digit of the answer. 
Result so far: 12654.0
If we take 1368 away from 1577, we end up with 209.
Grab the next digit (7) from the dividend, add it to 209, then carry on: 2097 / 342

Step 8:
The number 342 fits into 2097 6 times, leaving a remainder of 45.
Use 6 as the next digit of our solution. 
Result so far: 126546.0
Deduct 2052 from 2097 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
If we divide 450 by 342, we get 1 and a remainder of 108.
Use 1 as the next digit of our solution. 
Result so far: 126546.1
Subtracting 342 from 450 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 10:
The number 342 fits into 1080 3 times, leaving a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 126546.13
Subtracting 1026 from 1080 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 11:
When dividing 540 by 342, we get 1 with a remainder of 198.
The next digit of our result is 1. 
Result so far: 126546.131
Subtract 342 from 540 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 12:
342 can be fit into 1980 5 times, resulting in a remainder of 270.
Record the quotient 5 as the next digit in the result. 
Result so far: 126546.1315
Subtracting 1710 from 1980 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 13:
When dividing 2700 by 342, we get 7 with a remainder of 306.
Write down 7 as next digit of the result. 
Result so far: 126546.13157
Subtracting 2394 from 2700 leaves us with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 14:
342 goes into 3060 8 times with a remainder of 324.
Record the quotient 8 as the next digit in the result. 
Result so far: 126546.131578
If we take 2736 away from 3060, we end up with 324.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

On to step 15:
The number 342 fits into 3240 9 times, leaving a remainder of 162.
Record the quotient 9 as the next digit in the result. 
Result so far: 126546.1315789
Subtract 3078 from 3240 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Let's proceed to step 16:
The number 342 fits into 1620 4 times, leaving a remainder of 252.
The number 4 becomes the next digit in our result. 
Result so far: 126546.13157894
If we subtract 1368 from 1620, we get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

After the division, we end up with 126546.13157894 and a remainder of 2.52e-07.
