We look at the division of 63735550 by 126 
We're looking to find how many times 126 goes into 63735550.

Advancing to step 1:
126 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 126

Advancing to step 2:
126 can be fit into 63 0 times, resulting in a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Bring next digit (7) of the dividend behind the 63 and repeat the process: 637 / 126

Going ahead to step 3:
When dividing 637 by 126, we get 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 630 from 637, we get 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 126

Step 4:
126 can be fit into 73 0 times, resulting in a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 73 to get 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 126

Step 5:
When dividing 735 by 126, we get 5 with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 505.0
Subtract 630 from 735 to get 105.
Fetch the next digit (5) from the dividend, attach it to 105 and continue: 1055 / 126

Going ahead to step 6:
1055 divided by 126 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 5058.0
Subtract 1008 from 1055 to get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 126

Going ahead to step 7:
If we divide 475 by 126, we get 3 and a remainder of 97.
Write down 3 as next digit of the result. 
Result so far: 50583.0
Subtract 378 from 475 to get 97.
Append the next digit (0) from the dividend to 97 and continue with: 970 / 126

Moving on to step 8:
970 divided by 126 is 7 with a remainder of 88.
Write down 7 as next digit of the result. 
Result so far: 505837.0
Deduct 882 from 970 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 9:
126 can be fit into 880 6 times, resulting in a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 505837.6
Deduct 756 from 880 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 10:
1240 divided by 126 is 9 with a remainder of 106.
Record the quotient 9 as the next digit in the result. 
Result so far: 505837.69
Subtract 1134 from 1240 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 11:
The number 126 fits into 1060 8 times, leaving a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 505837.698
The remainder is 52 after subtracting 1008 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 12:
The number 126 fits into 520 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 505837.6984
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
126 goes into 160 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 505837.69841
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
340 divided by 126 is 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 505837.698412
Subtract 252 from 340 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 15:
126 goes into 880 6 times with a remainder of 124.
Use 6 as the next digit of our solution. 
Result so far: 505837.6984126
Subtract 756 from 880 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 16:
The number 126 fits into 1240 9 times, leaving a remainder of 106.
Write down 9 as next digit of the result. 
Result so far: 505837.69841269
If we take 1134 away from 1240, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

The final result is 505837.69841269 with a remainder of 1.06e-07.
