We look at the division of 797664 by 63 
We want to figure out the number of times 797664 can be divided by 63.

Step 1:
63 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 63

On to step 2:
63 goes into 79 1 times with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 16 after subtracting 63 from 79.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 63

Let's proceed to step 3:
When dividing 167 by 63, we get 2 with a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 126 from 167, we get 41.
Include the next digit (6) from the dividend after 41, then repeat: 416 / 63

On to step 4:
63 can be fit into 416 6 times, resulting in a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 378 from 416 and we're left with 38.
Bring next digit (6) of the dividend behind the 38 and repeat the process: 386 / 63

Moving on to step 5:
63 goes into 386 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 1266.0
Subtract 378 from 386 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 63

Advancing to step 6:
63 can be fit into 84 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 12661.0
The remainder is 21 after subtracting 63 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 63 fits into 210 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 12661.3
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
210 divided by 63 is 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 12661.33
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 12661.33 with a remainder of 0.021.
