4906821 ÷ 505 
We're looking to find how many times 505 goes into 4906821.

On to step 1:
When dividing 4 by 505, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 505

Going ahead to step 2:
505 can be fit into 49 0 times, resulting in a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 505

Moving on to step 3:
505 goes into 490 0 times with a remainder of 490.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 490 and we're left with 490.
Append the next digit (6) from the dividend to 490 and continue with: 4906 / 505

Going ahead to step 4:
4906 divided by 505 is 9 with a remainder of 361.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 4545 from 4906 to get 361.
Include the next digit (8) from the dividend after 361, then repeat: 3618 / 505

On to step 5:
3618 divided by 505 is 7 with a remainder of 83.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we take 3535 away from 3618, we end up with 83.
Fetch the next digit (2) from the dividend, attach it to 83 and continue: 832 / 505

Going ahead to step 6:
832 divided by 505 is 1 with a remainder of 327.
Record the quotient 1 as the next digit in the result. 
Result so far: 971.0
If we take 505 away from 832, we end up with 327.
Append the next digit (1) from the dividend to 327 and continue with: 3271 / 505

Going ahead to step 7:
If we divide 3271 by 505, we get 6 and a remainder of 241.
Put 6 as the next digit of the answer. 
Result so far: 9716.0
Subtract 3030 from 3271 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Let's proceed to step 8:
505 can be fit into 2410 4 times, resulting in a remainder of 390.
The number 4 becomes the next digit in our result. 
Result so far: 9716.4
Subtracting 2020 from 2410 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Advancing to step 9:
When dividing 3900 by 505, we get 7 with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 9716.47
Subtract 3535 from 3900 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
The number 505 fits into 3650 7 times, leaving a remainder of 115.
Write down 7 as next digit of the result. 
Result so far: 9716.477
The remainder is 115 after subtracting 3535 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final outcome is 9716.477, with a leftover of 0.0115.
