We're dividing 48271593 by 126 
We want to divide 48271593 by 126.

Step 1:
If we divide 4 by 126, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 126

Let's proceed to step 2:
When dividing 48 by 126, we get 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (2) from the dividend, attach it to 48 and continue: 482 / 126

Going ahead to step 3:
482 divided by 126 is 3 with a remainder of 104.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 378 away from 482, we end up with 104.
Fetch the next digit (7) from the dividend, attach it to 104 and continue: 1047 / 126

On to step 4:
1047 divided by 126 is 8 with a remainder of 39.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 1008 away from 1047, we end up with 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 126

Step 5:
126 can be fit into 391 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 383.0
Deduct 378 from 391 and we're left with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 126

Step 6:
126 goes into 135 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 3831.0
The remainder is 9 after subtracting 126 from 135.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 126

On to step 7:
126 goes into 99 0 times with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 38310.0
If we subtract 0 from 99, we get 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 126

Step 8:
If we divide 993 by 126, we get 7 and a remainder of 111.
Use 7 as the next digit of our solution. 
Result so far: 383107.0
Subtract 882 from 993 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Going ahead to step 9:
126 can be fit into 1110 8 times, resulting in a remainder of 102.
The number 8 becomes the next digit in our result. 
Result so far: 383107.8
Deduct 1008 from 1110 and we're left 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.

Moving on to step 10:
If we divide 1020 by 126, we get 8 and a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 383107.88
Subtracting 1008 from 1020 leaves us 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.

The final result is 383107.88 with a remainder of 0.012.
