We look at the division of 817964 by 63 
Our goal is to divide 817964 by 63.

Let's proceed to step 1:
63 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 63

Let's proceed to step 2:
63 can be fit into 81 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 63 from 81 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 63

On to step 3:
63 can be fit into 187 2 times, resulting in a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 126 from 187 leaves us with 61.
Take the next digit (9) from the dividend and append it to 61, then repeat: 619 / 63

Going ahead to step 4:
The number 63 fits into 619 9 times, leaving a remainder of 52.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
Subtract 567 from 619 to get 52.
Grab the next digit (6) from the dividend, add it to 52, then carry on: 526 / 63

On to step 5:
If we divide 526 by 63, we get 8 and a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1298.0
Deduct 504 from 526 and we're left with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 63

Step 6:
224 divided by 63 is 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 12983.0
If we take 189 away from 224, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 63 fits into 350 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 12983.5
If we subtract 315 from 350, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
63 can be fit into 350 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12983.55
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 12983.55, with a leftover of 0.035.
