43425206 ÷ 126 
Our goal is to divide 43425206 by 126.

Moving on to step 1:
126 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 126

Step 2:
The number 126 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Include the next digit (4) from the dividend after 43, then repeat: 434 / 126

Step 3:
If we divide 434 by 126, we get 3 and a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 378 from 434 and we're left with 56.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 126

Step 4:
126 can be fit into 562 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 504 from 562 to get 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 126

Advancing to step 5:
126 goes into 585 4 times with a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 344.0
If we subtract 504 from 585, we get 81.
Append the next digit (2) from the dividend to 81 and continue with: 812 / 126

Moving on to step 6:
126 goes into 812 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 3446.0
Deduct 756 from 812 and we're left with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 126

Moving on to step 7:
When dividing 560 by 126, we get 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 34464.0
Subtract 504 from 560 to get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 126

Going ahead to step 8:
If we divide 566 by 126, we get 4 and a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 344644.0
If we subtract 504 from 566, 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 9:
620 divided by 126 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 344644.4
Subtract 504 from 620 to get 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 10:
The number 126 fits into 1160 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 344644.49
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.

Let's proceed to step 11:
260 divided by 126 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 344644.492
Subtracting 252 from 260 leaves us 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.

On to step 12:
80 divided by 126 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 344644.492
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 13:
If we divide 800 by 126, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 344644.49206
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
If we divide 440 by 126, we get 3 and a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 344644.492063
Subtracting 378 from 440 leaves us 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.

Step 15:
620 divided by 126 is 4 with a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 344644.4920634
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 16:
If we divide 1160 by 126, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 344644.49206349
Deduct 1134 from 1160 and we're left 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.

The quotient of the division is 344644.49206349, and the remainder is 2.6e-08.
