66660638 divided by 793 
We want to figure out the number of times 66660638 can be divided by 793.

Going ahead to step 1:
When dividing 6 by 793, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 793

Step 2:
If we divide 66 by 793, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 793

On to step 3:
If we divide 666 by 793, we get 0 and a remainder of 666.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 666 and we're left with 666.
Append the next digit (6) from the dividend to 666 and continue with: 6666 / 793

Advancing to step 4:
6666 divided by 793 is 8 with a remainder of 322.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 322 after subtracting 6344 from 6666.
Include the next digit (0) from the dividend after 322, then repeat: 3220 / 793

On to step 5:
3220 divided by 793 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 48 after subtracting 3172 from 3220.
Include the next digit (6) from the dividend after 48, then repeat: 486 / 793

On to step 6:
When dividing 486 by 793, we get 0 with a remainder of 486.
Record the quotient 0 as the next digit in the result. 
Result so far: 840.0
Deduct 0 from 486 and we're left with 486.
Append the next digit (3) from the dividend to 486 and continue with: 4863 / 793

Going ahead to step 7:
793 goes into 4863 6 times with a remainder of 105.
The number 6 becomes the next digit in our result. 
Result so far: 8406.0
Deduct 4758 from 4863 and we're left with 105.
Bring next digit (8) of the dividend behind the 105 and repeat the process: 1058 / 793

Let's proceed to step 8:
793 can be fit into 1058 1 times, resulting in a remainder of 265.
Record the quotient 1 as the next digit in the result. 
Result so far: 84061.0
If we take 793 away from 1058, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Step 9:
If we divide 2650 by 793, we get 3 and a remainder of 271.
The number 3 becomes the next digit in our result. 
Result so far: 84061.3
Subtract 2379 from 2650 to get 271.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2710, and continue the process.

On to step 10:
793 goes into 2710 3 times with a remainder of 331.
The next digit of our result is 3. 
Result so far: 84061.33
Subtracting 2379 from 2710 leaves us with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

After the division, we end up with 84061.33 and a remainder of 0.331.
