We're dividing 53082409 by 517 
We're looking to find how many times 517 goes into 53082409.

Let's proceed to step 1:
When dividing 5 by 517, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 517

Going ahead to step 2:
53 divided by 517 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 517

On to step 3:
530 divided by 517 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 13 after subtracting 517 from 530.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 517

Advancing to step 4:
If we divide 138 by 517, we get 0 and a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 138 and we're left with 138.
Grab the next digit (2) from the dividend, add it to 138, then carry on: 1382 / 517

Moving on to step 5:
517 can be fit into 1382 2 times, resulting in a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 1034 from 1382 leaves us with 348.
Append the next digit (4) from the dividend to 348 and continue with: 3484 / 517

Let's proceed to step 6:
When dividing 3484 by 517, we get 6 with a remainder of 382.
Record the quotient 6 as the next digit in the result. 
Result so far: 1026.0
Subtract 3102 from 3484 to get 382.
Bring next digit (0) of the dividend behind the 382 and repeat the process: 3820 / 517

Let's proceed to step 7:
If we divide 3820 by 517, we get 7 and a remainder of 201.
Write down 7 as next digit of the result. 
Result so far: 10267.0
If we take 3619 away from 3820, we end up with 201.
Fetch the next digit (9) from the dividend, attach it to 201 and continue: 2019 / 517

On to step 8:
When dividing 2019 by 517, we get 3 with a remainder of 468.
Record the quotient 3 as the next digit in the result. 
Result so far: 102673.0
Subtract 1551 from 2019 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Advancing to step 9:
517 can be fit into 4680 9 times, resulting in a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 102673.9
Deduct 4653 from 4680 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 10:
If we divide 270 by 517, we get 0 and a remainder of 270.
The next digit of our result is 0. 
Result so far: 102673.9
Subtract 0 from 270 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Advancing to step 11:
When dividing 2700 by 517, we get 5 with a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 102673.905
If we take 2585 away from 2700, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 12:
517 can be fit into 1150 2 times, resulting in a remainder of 116.
Write down 2 as next digit of the result. 
Result so far: 102673.9052
Deduct 1034 from 1150 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 13:
The number 517 fits into 1160 2 times, leaving a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 102673.90522
If we subtract 1034 from 1160, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

The final outcome is 102673.90522, with a leftover of 0.000126.
