52800869 ÷ 510 
We're looking to find how many times 510 goes into 52800869.

On to step 1:
510 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 510

Moving on to step 2:
510 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Bring next digit (8) of the dividend behind the 52 and repeat the process: 528 / 510

Going ahead to step 3:
510 can be fit into 528 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 510 from 528, we get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 510

Going ahead to step 4:
The number 510 fits into 180 0 times, leaving a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 180 after subtracting 0 from 180.
Take the next digit (0) from the dividend and append it to 180, then repeat: 1800 / 510

Advancing to step 5:
When dividing 1800 by 510, we get 3 with a remainder of 270.
The next digit of our result is 3. 
Result so far: 103.0
Deduct 1530 from 1800 and we're left with 270.
Grab the next digit (8) from the dividend, add it to 270, then carry on: 2708 / 510

Going ahead to step 6:
The number 510 fits into 2708 5 times, leaving a remainder of 158.
Write down 5 as next digit of the result. 
Result so far: 1035.0
If we take 2550 away from 2708, we end up with 158.
Fetch the next digit (6) from the dividend, attach it to 158 and continue: 1586 / 510

Let's proceed to step 7:
The number 510 fits into 1586 3 times, leaving a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 10353.0
Subtract 1530 from 1586 to get 56.
Fetch the next digit (9) from the dividend, attach it to 56 and continue: 569 / 510

Advancing to step 8:
569 divided by 510 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 103531.0
Subtracting 510 from 569 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
The number 510 fits into 590 1 times, leaving a remainder of 80.
The next digit of our result is 1. 
Result so far: 103531.1
Subtract 510 from 590 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
The number 510 fits into 800 1 times, leaving a remainder of 290.
Use 1 as the next digit of our solution. 
Result so far: 103531.11
The remainder is 290 after subtracting 510 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Our division results in 103531.11 with a remaining 0.29.
