If we divide 5 by 505, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 505

Moving on to step 2:
505 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 505

Advancing to step 3:
If we divide 501 by 505, we get 0 and a remainder of 501.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 501, we end up with 501.
Bring next digit (0) of the dividend behind the 501 and repeat the process: 5010 / 505

Going ahead to step 4:
505 can be fit into 5010 9 times, resulting in a remainder of 465.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 4545 from 5010 and we're left with 465.
Take the next digit (2) from the dividend and append it to 465, then repeat: 4652 / 505

Moving on to step 5:
The number 505 fits into 4652 9 times, leaving a remainder of 107.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 107 after subtracting 4545 from 4652.
Grab the next digit (6) from the dividend, add it to 107, then carry on: 1076 / 505

Advancing to step 6:
1076 divided by 505 is 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 992.0
Deduct 1010 from 1076 and we're left with 66.
Include the next digit (1) from the dividend after 66, then repeat: 661 / 505

Moving on to step 7:
If we divide 661 by 505, we get 1 and a remainder of 156.
Write down 1 as next digit of the result. 
Result so far: 9921.0
Subtracting 505 from 661 leaves us with 156.
Grab the next digit (9) from the dividend, add it to 156, then carry on: 1569 / 505

Going ahead to step 8:
If we divide 1569 by 505, we get 3 and a remainder of 54.
The number 3 becomes the next digit in our result. 
Result so far: 99213.0
Deduct 1515 from 1569 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
505 goes into 540 1 times with a remainder of 35.
Put 1 as the next digit of the answer. 
Result so far: 99213.1
Deduct 505 from 540 and we're left 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.

Step 10:
350 divided by 505 is 0 with a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 99213.1
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 11:
3500 divided by 505 is 6 with a remainder of 470.
Put 6 as the next digit of the answer. 
Result so far: 99213.106
The remainder is 470 after subtracting 3030 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 12:
When dividing 4700 by 505, we get 9 with a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 99213.1069
Deduct 4545 from 4700 and we're left with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 13:
505 goes into 1550 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 99213.10693
The remainder is 35 after subtracting 1515 from 1550.
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 14:
If we divide 350 by 505, we get 0 and a remainder of 350.
The next digit of our result is 0. 
Result so far: 99213.10693
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 15:
505 goes into 3500 6 times with a remainder of 470.
Put 6 as the next digit of the answer. 
Result so far: 99213.1069306
Deduct 3030 from 3500 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Moving on to step 16:
If we divide 4700 by 505, we get 9 and a remainder of 155.
The number 9 becomes the next digit in our result. 
Result so far: 99213.10693069
Subtracting 4545 from 4700 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.
