42731153 ÷ 126 
Let's see how many times 126 fits into 42731153.

Moving on to step 1:
126 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 126

Going ahead to step 2:
126 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (7) from the dividend after 42, then repeat: 427 / 126

Let's proceed to step 3:
The number 126 fits into 427 3 times, leaving a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 378 from 427, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 126

On to step 4:
126 can be fit into 493 3 times, resulting in a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 378 away from 493, we end up with 115.
Grab the next digit (1) from the dividend, add it to 115, then carry on: 1151 / 126

Going ahead to step 5:
126 can be fit into 1151 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 339.0
Deduct 1134 from 1151 and we're left with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 126

Step 6:
The number 126 fits into 171 1 times, leaving a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 3391.0
Subtract 126 from 171 to get 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 126

Step 7:
455 divided by 126 is 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 33913.0
If we take 378 away from 455, we end up with 77.
Fetch the next digit (3) from the dividend, attach it to 77 and continue: 773 / 126

Let's proceed to step 8:
The number 126 fits into 773 6 times, leaving a remainder of 17.
The next digit of our result is 6. 
Result so far: 339136.0
If we subtract 756 from 773, we 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 9:
170 divided by 126 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 339136.1
Deduct 126 from 170 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
126 goes into 440 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 339136.13
If we subtract 378 from 440, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 11:
126 can be fit into 620 4 times, resulting in a remainder of 116.
Use 4 as the next digit of our solution. 
Result so far: 339136.134
Deduct 504 from 620 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
126 goes into 1160 9 times with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 339136.1349
If we take 1134 away from 1160, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
If we divide 260 by 126, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 339136.13492
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
80 divided by 126 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 339136.13492
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 15:
126 can be fit into 800 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 339136.1349206
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 16:
The number 126 fits into 440 3 times, leaving a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 339136.13492063
Deduct 378 from 440 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 339136.13492063 with a remainder of 6.2e-08.
