We look at the division of 4501971 by 510 
Let's see how many times 510 fits into 4501971.

Moving on to step 1:
If we divide 4 by 510, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 510

Advancing to step 2:
If we divide 45 by 510, we get 0 and a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 510

Advancing to step 3:
450 divided by 510 is 0 with a remainder of 450.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 450 leaves us with 450.
Fetch the next digit (1) from the dividend, attach it to 450 and continue: 4501 / 510

Moving on to step 4:
The number 510 fits into 4501 8 times, leaving a remainder of 421.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 4080 from 4501, we get 421.
Take the next digit (9) from the dividend and append it to 421, then repeat: 4219 / 510

On to step 5:
The number 510 fits into 4219 8 times, leaving a remainder of 139.
Put 8 as the next digit of the answer. 
Result so far: 88.0
Deduct 4080 from 4219 and we're left with 139.
Grab the next digit (7) from the dividend, add it to 139, then carry on: 1397 / 510

Moving on to step 6:
510 goes into 1397 2 times with a remainder of 377.
The next digit of our result is 2. 
Result so far: 882.0
If we take 1020 away from 1397, we end up with 377.
Include the next digit (1) from the dividend after 377, then repeat: 3771 / 510

Moving on to step 7:
510 goes into 3771 7 times with a remainder of 201.
The number 7 becomes the next digit in our result. 
Result so far: 8827.0
Subtract 3570 from 3771 to get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Moving on to step 8:
510 can be fit into 2010 3 times, resulting in a remainder of 480.
Record the quotient 3 as the next digit in the result. 
Result so far: 8827.3
Subtracting 1530 from 2010 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 9:
If we divide 4800 by 510, we get 9 and a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 8827.39
If we subtract 4590 from 4800, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 10:
2100 divided by 510 is 4 with a remainder of 60.
The next digit of our result is 4. 
Result so far: 8827.394
Subtract 2040 from 2100 to 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:
510 can be fit into 600 1 times, resulting in a remainder of 90.
Use 1 as the next digit of our solution. 
Result so far: 8827.3941
Subtracting 510 from 600 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 12:
When dividing 900 by 510, we get 1 with a remainder of 390.
The next digit of our result is 1. 
Result so far: 8827.39411
If we take 510 away from 900, we end up 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.

The final result is 8827.39411 with a remainder of 0.00039.
