We're dividing 57225243 by 126 
We want to divide 57225243 by 126.

Moving on to step 1:
126 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 126

Going ahead to step 2:
126 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 126

Advancing to step 3:
The number 126 fits into 572 4 times, leaving a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 68 after subtracting 504 from 572.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 126

Advancing to step 4:
When dividing 682 by 126, we get 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
If we take 630 away from 682, we end up with 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 126

Let's proceed to step 5:
If we divide 525 by 126, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 454.0
If we take 504 away from 525, we end up with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 126

Advancing to step 6:
212 divided by 126 is 1 with a remainder of 86.
Put 1 as the next digit of the answer. 
Result so far: 4541.0
If we take 126 away from 212, we end up with 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 126

Moving on to step 7:
864 divided by 126 is 6 with a remainder of 108.
Record the quotient 6 as the next digit in the result. 
Result so far: 45416.0
Subtracting 756 from 864 leaves us with 108.
Fetch the next digit (3) from the dividend, attach it to 108 and continue: 1083 / 126

Moving on to step 8:
If we divide 1083 by 126, we get 8 and a remainder of 75.
The next digit of our result is 8. 
Result so far: 454168.0
If we subtract 1008 from 1083, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 9:
The number 126 fits into 750 5 times, leaving a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 454168.5
The remainder is 120 after subtracting 630 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 10:
126 can be fit into 1200 9 times, resulting in a remainder of 66.
Put 9 as the next digit of the answer. 
Result so far: 454168.59
The remainder is 66 after subtracting 1134 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 11:
126 can be fit into 660 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 454168.595
Subtract 630 from 660 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 126, we get 2 and a remainder of 48.
The next digit of our result is 2. 
Result so far: 454168.5952
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
The number 126 fits into 480 3 times, leaving a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 454168.59523
Subtracting 378 from 480 leaves us with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 14:
The number 126 fits into 1020 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 454168.595238
If we take 1008 away from 1020, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 15:
If we divide 120 by 126, we get 0 and a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 454168.595238
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 16:
The number 126 fits into 1200 9 times, leaving a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 454168.59523809
If we subtract 1134 from 1200, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The quotient of the division is 454168.59523809, and the remainder is 6.6e-08.
