We're dividing 63654919 by 630 
We want to divide 63654919 by 630.

Moving on to step 1:
630 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 630

Going ahead to step 2:
63 divided by 630 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Include the next digit (6) from the dividend after 63, then repeat: 636 / 630

Moving on to step 3:
630 can be fit into 636 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 630 from 636 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 630

On to step 4:
630 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 65 leaves us with 65.
Fetch the next digit (4) from the dividend, attach it to 65 and continue: 654 / 630

On to step 5:
654 divided by 630 is 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 101.0
Deduct 630 from 654 and we're left with 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 630

Going ahead to step 6:
If we divide 249 by 630, we get 0 and a remainder of 249.
Write down 0 as next digit of the result. 
Result so far: 1010.0
Subtracting 0 from 249 leaves us with 249.
Fetch the next digit (1) from the dividend, attach it to 249 and continue: 2491 / 630

Let's proceed to step 7:
630 goes into 2491 3 times with a remainder of 601.
Record the quotient 3 as the next digit in the result. 
Result so far: 10103.0
If we take 1890 away from 2491, we end up with 601.
Include the next digit (9) from the dividend after 601, then repeat: 6019 / 630

Let's proceed to step 8:
6019 divided by 630 is 9 with a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 101039.0
Subtracting 5670 from 6019 leaves us with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
3490 divided by 630 is 5 with a remainder of 340.
The number 5 becomes the next digit in our result. 
Result so far: 101039.5
The remainder is 340 after subtracting 3150 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 10:
630 can be fit into 3400 5 times, resulting in a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 101039.55
If we subtract 3150 from 3400, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Our division results in 101039.55 with a remaining 0.25.
