We're dividing 66716812 by 517 
We're looking to find how many times 517 goes into 66716812.

On to step 1:
If we divide 6 by 517, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 517

Step 2:
517 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 517

On to step 3:
The number 517 fits into 667 1 times, leaving a remainder of 150.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 150 after subtracting 517 from 667.
Append the next digit (1) from the dividend to 150 and continue with: 1501 / 517

Going ahead to step 4:
1501 divided by 517 is 2 with a remainder of 467.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 1034 from 1501 to get 467.
Bring next digit (6) of the dividend behind the 467 and repeat the process: 4676 / 517

On to step 5:
If we divide 4676 by 517, we get 9 and a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Subtracting 4653 from 4676 leaves us with 23.
Fetch the next digit (8) from the dividend, attach it to 23 and continue: 238 / 517

Step 6:
When dividing 238 by 517, we get 0 with a remainder of 238.
Put 0 as the next digit of the answer. 
Result so far: 1290.0
If we take 0 away from 238, we end up with 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 517

Moving on to step 7:
The number 517 fits into 2381 4 times, leaving a remainder of 313.
Use 4 as the next digit of our solution. 
Result so far: 12904.0
If we take 2068 away from 2381, we end up with 313.
Bring next digit (2) of the dividend behind the 313 and repeat the process: 3132 / 517

Going ahead to step 8:
517 goes into 3132 6 times with a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 129046.0
If we subtract 3102 from 3132, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
517 can be fit into 300 0 times, resulting in a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 129046.0
Deduct 0 from 300 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
517 can be fit into 3000 5 times, resulting in a remainder of 415.
Record the quotient 5 as the next digit in the result. 
Result so far: 129046.05
If we take 2585 away from 3000, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 11:
517 can be fit into 4150 8 times, resulting in a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 129046.058
If we subtract 4136 from 4150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
517 can be fit into 140 0 times, resulting in a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 129046.058
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
The number 517 fits into 1400 2 times, leaving a remainder of 366.
Put 2 as the next digit of the answer. 
Result so far: 129046.05802
If we subtract 1034 from 1400, we get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 14:
517 can be fit into 3660 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 129046.058027
If we take 3619 away from 3660, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 15:
410 divided by 517 is 0 with a remainder of 410.
Write down 0 as next digit of the result. 
Result so far: 129046.058027
Subtracting 0 from 410 leaves us with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Let's proceed to step 16:
If we divide 4100 by 517, we get 7 and a remainder of 481.
Use 7 as the next digit of our solution. 
Result so far: 129046.05802707
Deduct 3619 from 4100 and we're left with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

After the division, we end up with 129046.05802707 and a remainder of 4.81e-07.
