We're dividing 52807942 by 515 
We're looking to find how many times 515 goes into 52807942.

Going ahead to step 1:
If we divide 5 by 515, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 515

Going ahead to step 2:
52 divided by 515 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 515

Let's proceed to step 3:
528 divided by 515 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 515 from 528 leaves us with 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 515

Advancing to step 4:
The number 515 fits into 130 0 times, leaving a remainder of 130.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 130, we get 130.
Fetch the next digit (7) from the dividend, attach it to 130 and continue: 1307 / 515

Let's proceed to step 5:
515 can be fit into 1307 2 times, resulting in a remainder of 277.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 1030 away from 1307, we end up with 277.
Append the next digit (9) from the dividend to 277 and continue with: 2779 / 515

Moving on to step 6:
If we divide 2779 by 515, we get 5 and a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 1025.0
The remainder is 204 after subtracting 2575 from 2779.
Fetch the next digit (4) from the dividend, attach it to 204 and continue: 2044 / 515

Advancing to step 7:
2044 divided by 515 is 3 with a remainder of 499.
Record the quotient 3 as the next digit in the result. 
Result so far: 10253.0
Deduct 1545 from 2044 and we're left with 499.
Grab the next digit (2) from the dividend, add it to 499, then carry on: 4992 / 515

On to step 8:
515 can be fit into 4992 9 times, resulting in a remainder of 357.
Use 9 as the next digit of our solution. 
Result so far: 102539.0
Subtract 4635 from 4992 to get 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Going ahead to step 9:
If we divide 3570 by 515, we get 6 and a remainder of 480.
Use 6 as the next digit of our solution. 
Result so far: 102539.6
Deduct 3090 from 3570 and we're left 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.

Let's proceed to step 10:
When dividing 4800 by 515, we get 9 with a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 102539.69
If we subtract 4635 from 4800, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 11:
If we divide 1650 by 515, we get 3 and a remainder of 105.
Put 3 as the next digit of the answer. 
Result so far: 102539.693
Deduct 1545 from 1650 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 12:
When dividing 1050 by 515, we get 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 102539.6932
Subtract 1030 from 1050 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
If we divide 200 by 515, we get 0 and a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 102539.6932
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 14:
When dividing 2000 by 515, we get 3 with a remainder of 455.
The next digit of our result is 3. 
Result so far: 102539.693203
The remainder is 455 after subtracting 1545 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4550, and continue the process.

Advancing to step 15:
If we divide 4550 by 515, we get 8 and a remainder of 430.
The next digit of our result is 8. 
Result so far: 102539.6932038
Deduct 4120 from 4550 and we're left with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 16:
4300 divided by 515 is 8 with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 102539.69320388
If we subtract 4120 from 4300, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

The final result is 102539.69320388 with a remainder of 1.8e-07.
