Let's divide 63900034 by 63
Let's see how many times 63 fits into 63900034.

Advancing to step 1:
63 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 63

Let's proceed to step 2:
63 can be fit into 63 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 63 from 63.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 63

Advancing to step 3:
When dividing 9 by 63, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 63

Moving on to step 4:
63 can be fit into 90 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 63 away from 90, we end up with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 63

Going ahead to step 5:
63 goes into 270 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1014.0
Subtracting 252 from 270 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 63

Going ahead to step 6:
When dividing 180 by 63, we get 2 with a remainder of 54.
Write down 2 as next digit of the result. 
Result so far: 10142.0
Subtracting 126 from 180 leaves us with 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 63

Advancing to step 7:
When dividing 543 by 63, we get 8 with a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 101428.0
If we subtract 504 from 543, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 63

Advancing to step 8:
The number 63 fits into 394 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 1014286.0
Subtracting 378 from 394 leaves us with 16.
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 9:
63 goes into 160 2 times with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 1014286.2
If we take 126 away from 160, we end up 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.

Let's proceed to step 10:
63 goes into 340 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 1014286.25
Subtract 315 from 340 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
When dividing 250 by 63, we get 3 with a remainder of 61.
The number 3 becomes the next digit in our result. 
Result so far: 1014286.253
Subtracting 189 from 250 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 12:
610 divided by 63 is 9 with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 1014286.2539
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
63 can be fit into 430 6 times, resulting in a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 1014286.25396
If we subtract 378 from 430, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 14:
63 can be fit into 520 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1014286.253968
Subtracting 504 from 520 leaves us with 16.
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 15:
63 goes into 160 2 times with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 1014286.2539682
Subtracting 126 from 160 leaves us 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.

Advancing to step 16:
When dividing 340 by 63, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 1014286.25396825
If we take 315 away from 340, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The final result is 1014286.25396825 with a remainder of 2.5e-08.
