66320610 ÷ 517 
Let's see how many times 517 fits into 66320610.

Advancing to step 1:
When dividing 6 by 517, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 517

Let's proceed to step 2:
If we divide 66 by 517, we get 0 and a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 517

Advancing to step 3:
If we divide 663 by 517, we get 1 and a remainder of 146.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 517 away from 663, we end up with 146.
Append the next digit (2) from the dividend to 146 and continue with: 1462 / 517

Advancing to step 4:
The number 517 fits into 1462 2 times, leaving a remainder of 428.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 1034 from 1462, we get 428.
Grab the next digit (0) from the dividend, add it to 428, then carry on: 4280 / 517

Moving on to step 5:
517 goes into 4280 8 times with a remainder of 144.
Put 8 as the next digit of the answer. 
Result so far: 128.0
Subtracting 4136 from 4280 leaves us with 144.
Append the next digit (6) from the dividend to 144 and continue with: 1446 / 517

Let's proceed to step 6:
If we divide 1446 by 517, we get 2 and a remainder of 412.
Record the quotient 2 as the next digit in the result. 
Result so far: 1282.0
Subtract 1034 from 1446 to get 412.
Append the next digit (1) from the dividend to 412 and continue with: 4121 / 517

Step 7:
517 goes into 4121 7 times with a remainder of 502.
Put 7 as the next digit of the answer. 
Result so far: 12827.0
If we subtract 3619 from 4121, we get 502.
Take the next digit (0) from the dividend and append it to 502, then repeat: 5020 / 517

Let's proceed to step 8:
The number 517 fits into 5020 9 times, leaving a remainder of 367.
The number 9 becomes the next digit in our result. 
Result so far: 128279.0
If we subtract 4653 from 5020, we get 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Going ahead to step 9:
517 can be fit into 3670 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 128279.7
The remainder is 51 after subtracting 3619 from 3670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 10:
When dividing 510 by 517, we get 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 128279.7
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 11:
517 can be fit into 5100 9 times, resulting in a remainder of 447.
Record the quotient 9 as the next digit in the result. 
Result so far: 128279.709
If we take 4653 away from 5100, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Advancing to step 12:
4470 divided by 517 is 8 with a remainder of 334.
The number 8 becomes the next digit in our result. 
Result so far: 128279.7098
If we take 4136 away from 4470, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
517 goes into 3340 6 times with a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 128279.70986
Deduct 3102 from 3340 and we're left with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 14:
2380 divided by 517 is 4 with a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 128279.709864
If we take 2068 away from 2380, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
The number 517 fits into 3120 6 times, leaving a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 128279.7098646
Deduct 3102 from 3120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 16:
180 divided by 517 is 0 with a remainder of 180.
Write down 0 as next digit of the result. 
Result so far: 128279.7098646
The remainder is 180 after subtracting 0 from 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 outcome is 128279.7098646, with a leftover of 1.8e-07.
