64128306 ÷ 517 
Let's see how many times 517 fits into 64128306.

Advancing to step 1:
If we divide 6 by 517, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 517

Step 2:
64 divided by 517 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 517

On to step 3:
The number 517 fits into 641 1 times, leaving a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 517 from 641 leaves us with 124.
Append the next digit (2) from the dividend to 124 and continue with: 1242 / 517

On to step 4:
517 can be fit into 1242 2 times, resulting in a remainder of 208.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 208 after subtracting 1034 from 1242.
Fetch the next digit (8) from the dividend, attach it to 208 and continue: 2088 / 517

On to step 5:
When dividing 2088 by 517, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 124.0
The remainder is 20 after subtracting 2068 from 2088.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 517

Moving on to step 6:
When dividing 203 by 517, we get 0 with a remainder of 203.
The next digit of our result is 0. 
Result so far: 1240.0
If we take 0 away from 203, we end up with 203.
Append the next digit (0) from the dividend to 203 and continue with: 2030 / 517

Let's proceed to step 7:
When dividing 2030 by 517, we get 3 with a remainder of 479.
Record the quotient 3 as the next digit in the result. 
Result so far: 12403.0
If we take 1551 away from 2030, we end up with 479.
Append the next digit (6) from the dividend to 479 and continue with: 4796 / 517

Going ahead to step 8:
When dividing 4796 by 517, we get 9 with a remainder of 143.
The number 9 becomes the next digit in our result. 
Result so far: 124039.0
Deduct 4653 from 4796 and we're left with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
If we divide 1430 by 517, we get 2 and a remainder of 396.
Record the quotient 2 as the next digit in the result. 
Result so far: 124039.2
The remainder is 396 after subtracting 1034 from 1430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Advancing to step 10:
3960 divided by 517 is 7 with a remainder of 341.
Put 7 as the next digit of the answer. 
Result so far: 124039.27
If we take 3619 away from 3960, we end up with 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Moving on to step 11:
The number 517 fits into 3410 6 times, leaving a remainder of 308.
Record the quotient 6 as the next digit in the result. 
Result so far: 124039.276
The remainder is 308 after subtracting 3102 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 12:
517 goes into 3080 5 times with a remainder of 495.
The number 5 becomes the next digit in our result. 
Result so far: 124039.2765
If we subtract 2585 from 3080, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 13:
When dividing 4950 by 517, we get 9 with a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 124039.27659
If we subtract 4653 from 4950, we get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 14:
The number 517 fits into 2970 5 times, leaving a remainder of 385.
Put 5 as the next digit of the answer. 
Result so far: 124039.276595
Deduct 2585 from 2970 and we're left with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Let's proceed to step 15:
When dividing 3850 by 517, we get 7 with a remainder of 231.
Write down 7 as next digit of the result. 
Result so far: 124039.2765957
Subtracting 3619 from 3850 leaves us with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

Let's proceed to step 16:
517 goes into 2310 4 times with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 124039.27659574
Subtracting 2068 from 2310 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

After the division, we end up with 124039.27659574 and a remainder of 2.42e-07.
