63648172 ÷ 818 
Our goal is to divide 63648172 by 818.

On to step 1:
If we divide 6 by 818, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 818

Step 2:
818 can be fit into 63 0 times, resulting in 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.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 818

Moving on to step 3:
636 divided by 818 is 0 with a remainder of 636.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 636, we get 636.
Fetch the next digit (4) from the dividend, attach it to 636 and continue: 6364 / 818

Advancing to step 4:
When dividing 6364 by 818, we get 7 with a remainder of 638.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5726 from 6364, we get 638.
Take the next digit (8) from the dividend and append it to 638, then repeat: 6388 / 818

Let's proceed to step 5:
818 goes into 6388 7 times with a remainder of 662.
The number 7 becomes the next digit in our result. 
Result so far: 77.0
Subtracting 5726 from 6388 leaves us with 662.
Include the next digit (1) from the dividend after 662, then repeat: 6621 / 818

On to step 6:
If we divide 6621 by 818, we get 8 and a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
The remainder is 77 after subtracting 6544 from 6621.
Take the next digit (7) from the dividend and append it to 77, then repeat: 777 / 818

On to step 7:
818 goes into 777 0 times with a remainder of 777.
The next digit of our result is 0. 
Result so far: 7780.0
If we subtract 0 from 777, we get 777.
Include the next digit (2) from the dividend after 777, then repeat: 7772 / 818

Advancing to step 8:
7772 divided by 818 is 9 with a remainder of 410.
Use 9 as the next digit of our solution. 
Result so far: 77809.0
If we take 7362 away from 7772, we end up with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Step 9:
If we divide 4100 by 818, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 77809.5
Deduct 4090 from 4100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
The number 818 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 77809.5
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
When dividing 1000 by 818, we get 1 with a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 77809.501
Subtracting 818 from 1000 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 12:
818 goes into 1820 2 times with a remainder of 184.
Use 2 as the next digit of our solution. 
Result so far: 77809.5012
Subtract 1636 from 1820 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 13:
818 goes into 1840 2 times with a remainder of 204.
Write down 2 as next digit of the result. 
Result so far: 77809.50122
If we take 1636 away from 1840, we end up with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 77809.50122, with a leftover of 0.000204.
