65205857 ÷ 668 
We want to divide 65205857 by 668.

Going ahead to step 1:
668 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 668

Let's proceed to step 2:
668 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 668

Moving on to step 3:
652 divided by 668 is 0 with a remainder of 652.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 652 and we're left with 652.
Append the next digit (0) from the dividend to 652 and continue with: 6520 / 668

Going ahead to step 4:
The number 668 fits into 6520 9 times, leaving a remainder of 508.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 6012 from 6520, we get 508.
Fetch the next digit (5) from the dividend, attach it to 508 and continue: 5085 / 668

On to step 5:
668 can be fit into 5085 7 times, resulting in a remainder of 409.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Subtracting 4676 from 5085 leaves us with 409.
Fetch the next digit (8) from the dividend, attach it to 409 and continue: 4098 / 668

Step 6:
The number 668 fits into 4098 6 times, leaving a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 976.0
The remainder is 90 after subtracting 4008 from 4098.
Fetch the next digit (5) from the dividend, attach it to 90 and continue: 905 / 668

Going ahead to step 7:
668 goes into 905 1 times with a remainder of 237.
Record the quotient 1 as the next digit in the result. 
Result so far: 9761.0
Subtracting 668 from 905 leaves us with 237.
Fetch the next digit (7) from the dividend, attach it to 237 and continue: 2377 / 668

On to step 8:
668 goes into 2377 3 times with a remainder of 373.
Put 3 as the next digit of the answer. 
Result so far: 97613.0
The remainder is 373 after subtracting 2004 from 2377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Step 9:
The number 668 fits into 3730 5 times, leaving a remainder of 390.
The next digit of our result is 5. 
Result so far: 97613.5
The remainder is 390 after subtracting 3340 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 10:
668 goes into 3900 5 times with a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 97613.55
If we take 3340 away from 3900, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 97613.55, with a leftover of 0.56.
