80663205 ÷ 501 
We want to divide 80663205 by 501.

Advancing to step 1:
501 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
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 501

Going ahead to step 2:
When dividing 80 by 501, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (6) from the dividend after 80, then repeat: 806 / 501

Step 3:
If we divide 806 by 501, we get 1 and a remainder of 305.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 501 from 806 leaves us with 305.
Fetch the next digit (6) from the dividend, attach it to 305 and continue: 3056 / 501

Going ahead to step 4:
501 can be fit into 3056 6 times, resulting in a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 3006 from 3056 leaves us with 50.
Fetch the next digit (3) from the dividend, attach it to 50 and continue: 503 / 501

Moving on to step 5:
501 goes into 503 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 161.0
Deduct 501 from 503 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 501

Moving on to step 6:
If we divide 22 by 501, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 1610.0
The remainder is 22 after subtracting 0 from 22.
Bring next digit (0) of the dividend behind the 22 and repeat the process: 220 / 501

Going ahead to step 7:
If we divide 220 by 501, we get 0 and a remainder of 220.
Use 0 as the next digit of our solution. 
Result so far: 16100.0
If we take 0 away from 220, we end up with 220.
Take the next digit (5) from the dividend and append it to 220, then repeat: 2205 / 501

Moving on to step 8:
The number 501 fits into 2205 4 times, leaving a remainder of 201.
Record the quotient 4 as the next digit in the result. 
Result so far: 161004.0
Deduct 2004 from 2205 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Let's proceed to step 9:
2010 divided by 501 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 161004.4
Deduct 2004 from 2010 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
501 goes into 60 0 times with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 161004.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 11:
501 can be fit into 600 1 times, resulting in a remainder of 99.
The next digit of our result is 1. 
Result so far: 161004.401
Subtracting 501 from 600 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Let's proceed to step 12:
501 can be fit into 990 1 times, resulting in a remainder of 489.
Record the quotient 1 as the next digit in the result. 
Result so far: 161004.4011
The remainder is 489 after subtracting 501 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

The final result is 161004.4011 with a remainder of 0.00489.
