We look at the division of 63950540 by 512 
Let's see how many times 512 fits into 63950540.

Going ahead to step 1:
When dividing 6 by 512, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 512

Going ahead to step 2:
63 divided by 512 is 0 with a remainder of 63.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 512

Going ahead to step 3:
512 can be fit into 639 1 times, resulting in a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 512 from 639 leaves us with 127.
Fetch the next digit (5) from the dividend, attach it to 127 and continue: 1275 / 512

Moving on to step 4:
If we divide 1275 by 512, we get 2 and a remainder of 251.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1024 from 1275, we get 251.
Include the next digit (0) from the dividend after 251, then repeat: 2510 / 512

Going ahead to step 5:
512 goes into 2510 4 times with a remainder of 462.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
The remainder is 462 after subtracting 2048 from 2510.
Append the next digit (5) from the dividend to 462 and continue with: 4625 / 512

On to step 6:
When dividing 4625 by 512, we get 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 1249.0
Subtracting 4608 from 4625 leaves us with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 512

Step 7:
When dividing 174 by 512, we get 0 with a remainder of 174.
The number 0 becomes the next digit in our result. 
Result so far: 12490.0
Subtracting 0 from 174 leaves us with 174.
Fetch the next digit (0) from the dividend, attach it to 174 and continue: 1740 / 512

Step 8:
When dividing 1740 by 512, we get 3 with a remainder of 204.
Put 3 as the next digit of the answer. 
Result so far: 124903.0
Subtract 1536 from 1740 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 9:
The number 512 fits into 2040 3 times, leaving a remainder of 504.
The number 3 becomes the next digit in our result. 
Result so far: 124903.3
Subtract 1536 from 2040 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Advancing to step 10:
5040 divided by 512 is 9 with a remainder of 432.
Write down 9 as next digit of the result. 
Result so far: 124903.39
If we take 4608 away from 5040, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 11:
4320 divided by 512 is 8 with a remainder of 224.
Write down 8 as next digit of the result. 
Result so far: 124903.398
If we subtract 4096 from 4320, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
If we divide 2240 by 512, we get 4 and a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 124903.3984
If we subtract 2048 from 2240, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 13:
1920 divided by 512 is 3 with a remainder of 384.
Put 3 as the next digit of the answer. 
Result so far: 124903.39843
Deduct 1536 from 1920 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 14:
3840 divided by 512 is 7 with a remainder of 256.
The next digit of our result is 7. 
Result so far: 124903.398437
Subtract 3584 from 3840 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 15:
2560 divided by 512 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 124903.3984375
The remainder is 0 after subtracting 2560 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 16:
The number 512 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 124903.3984375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 124903.3984375, and the remainder is 0.0.
