Advancing to step 6:
449 divided by 126 is 3 with a remainder of 71.
The next digit of our result is 3. 
Result so far: 4273.0
If we take 378 away from 449, we end up with 71.
Bring next digit (0) of the dividend behind the 71 and repeat the process: 710 / 126

Advancing to step 7:
The number 126 fits into 710 5 times, leaving a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 42735.0
The remainder is 80 after subtracting 630 from 710.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 126

Advancing to step 8:
126 goes into 809 6 times with a remainder of 53.
Use 6 as the next digit of our solution. 
Result so far: 427356.0
Subtract 756 from 809 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 9:
530 divided by 126 is 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 427356.4
Subtracting 504 from 530 leaves us 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.

Going ahead to step 10:
The number 126 fits into 260 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 427356.42
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.

Step 11:
When dividing 80 by 126, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 427356.42
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.

Moving on to step 12:
When dividing 800 by 126, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 427356.4206
If we subtract 756 from 800, we get 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 13:
When dividing 440 by 126, we get 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 427356.42063
If we take 378 away from 440, we end up 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.

Advancing to step 14:
If we divide 620 by 126, we get 4 and a remainder of 116.
Record the quotient 4 as the next digit in the result. 
Result so far: 427356.420634
The remainder is 116 after subtracting 504 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 15:
126 goes into 1160 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 427356.4206349
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.

Advancing to step 16:
The number 126 fits into 260 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 427356.42063492
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 427356.42063492 with a remaining 8e-09.
