Let's divide 53787935 by 517
Our goal is to divide 53787935 by 517.

On to step 1:
The number 517 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 517

Let's proceed to step 2:
If we divide 53 by 517, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Fetch the next digit (7) from the dividend, attach it to 53 and continue: 537 / 517

Let's proceed to step 3:
The number 517 fits into 537 1 times, leaving a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 517 from 537 and we're left with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 517

On to step 4:
If we divide 208 by 517, we get 0 and a remainder of 208.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 208, we get 208.
Grab the next digit (7) from the dividend, add it to 208, then carry on: 2087 / 517

Step 5:
The number 517 fits into 2087 4 times, leaving a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we take 2068 away from 2087, we end up with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 517

Going ahead to step 6:
The number 517 fits into 199 0 times, leaving a remainder of 199.
Use 0 as the next digit of our solution. 
Result so far: 1040.0
If we take 0 away from 199, we end up with 199.
Bring next digit (3) of the dividend behind the 199 and repeat the process: 1993 / 517

Going ahead to step 7:
517 goes into 1993 3 times with a remainder of 442.
Record the quotient 3 as the next digit in the result. 
Result so far: 10403.0
Deduct 1551 from 1993 and we're left with 442.
Append the next digit (5) from the dividend to 442 and continue with: 4425 / 517

Let's proceed to step 8:
517 goes into 4425 8 times with a remainder of 289.
Use 8 as the next digit of our solution. 
Result so far: 104038.0
Subtracting 4136 from 4425 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Advancing to step 9:
2890 divided by 517 is 5 with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 104038.5
If we take 2585 away from 2890, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Let's proceed to step 10:
517 can be fit into 3050 5 times, resulting in a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 104038.55
Subtracting 2585 from 3050 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Our division results in 104038.55 with a remaining 0.465.
