We're dividing 664320 by 63 
We're looking to find how many times 63 goes into 664320.

On to step 1:
63 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
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 63

Going ahead to step 2:
If we divide 66 by 63, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 63 from 66 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 63

Step 3:
63 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 63

Going ahead to step 4:
343 divided by 63 is 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 105.0
The remainder is 28 after subtracting 315 from 343.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 63

Advancing to step 5:
63 can be fit into 282 4 times, resulting in a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 1054.0
The remainder is 30 after subtracting 252 from 282.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 63

Let's proceed to step 6:
When dividing 300 by 63, we get 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10544.0
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 7:
When dividing 480 by 63, we get 7 with a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 10544.7
Subtracting 441 from 480 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 8:
The number 63 fits into 390 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 10544.76
Subtract 378 from 390 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
When dividing 120 by 63, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 10544.761
If we take 63 away from 120, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 10:
The number 63 fits into 570 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 10544.7619
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 10544.7619
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
The number 63 fits into 300 4 times, leaving a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 10544.761904
If we subtract 252 from 300, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
When dividing 480 by 63, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 10544.7619047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
63 can be fit into 390 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10544.76190476
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 10544.76190476 and a remainder of 1.2e-08.
