We're dividing 64140265 by 126 
We want to divide 64140265 by 126.

On to step 1:
126 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 126

Let's proceed to step 2:
The number 126 fits into 64 0 times, leaving a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 126

Advancing to step 3:
126 can be fit into 641 5 times, resulting in a remainder of 11.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 11 after subtracting 630 from 641.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 126

Going ahead to step 4:
126 goes into 114 0 times with a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 50.0
If we subtract 0 from 114, we get 114.
Include the next digit (0) from the dividend after 114, then repeat: 1140 / 126

Moving on to step 5:
126 goes into 1140 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 509.0
If we subtract 1134 from 1140, we get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 126

Let's proceed to step 6:
126 goes into 62 0 times with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 5090.0
Subtracting 0 from 62 leaves us with 62.
Grab the next digit (6) from the dividend, add it to 62, then carry on: 626 / 126

On to step 7:
626 divided by 126 is 4 with a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 50904.0
Subtract 504 from 626 to get 122.
Bring next digit (5) of the dividend behind the 122 and repeat the process: 1225 / 126

Moving on to step 8:
If we divide 1225 by 126, we get 9 and a remainder of 91.
The number 9 becomes the next digit in our result. 
Result so far: 509049.0
Subtracting 1134 from 1225 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 9:
126 goes into 910 7 times with a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 509049.7
Subtracting 882 from 910 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.

On to step 10:
280 divided by 126 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 509049.72
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
126 can be fit into 280 2 times, resulting in a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 509049.722
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 509049.722 and a remainder of 0.0028.
