We look at the division of 66915882 by 993 
Our goal is to divide 66915882 by 993.

Moving on to step 1:
993 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 993

Advancing to step 2:
993 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 (9) of the dividend behind the 66 and repeat the process: 669 / 993

Let's proceed to step 3:
The number 993 fits into 669 0 times, leaving a remainder of 669.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 669, we get 669.
Grab the next digit (1) from the dividend, add it to 669, then carry on: 6691 / 993

Advancing to step 4:
993 can be fit into 6691 6 times, resulting in a remainder of 733.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 5958 away from 6691, we end up with 733.
Bring next digit (5) of the dividend behind the 733 and repeat the process: 7335 / 993

Let's proceed to step 5:
993 can be fit into 7335 7 times, resulting in a remainder of 384.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 6951 from 7335 to get 384.
Include the next digit (8) from the dividend after 384, then repeat: 3848 / 993

Going ahead to step 6:
3848 divided by 993 is 3 with a remainder of 869.
Put 3 as the next digit of the answer. 
Result so far: 673.0
If we subtract 2979 from 3848, we get 869.
Include the next digit (8) from the dividend after 869, then repeat: 8698 / 993

Moving on to step 7:
993 goes into 8698 8 times with a remainder of 754.
Write down 8 as next digit of the result. 
Result so far: 6738.0
The remainder is 754 after subtracting 7944 from 8698.
Take the next digit (2) from the dividend and append it to 754, then repeat: 7542 / 993

Moving on to step 8:
993 goes into 7542 7 times with a remainder of 591.
The number 7 becomes the next digit in our result. 
Result so far: 67387.0
Deduct 6951 from 7542 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Advancing to step 9:
993 can be fit into 5910 5 times, resulting in a remainder of 945.
Write down 5 as next digit of the result. 
Result so far: 67387.5
Subtracting 4965 from 5910 leaves us with 945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9450, and continue the process.

Advancing to step 10:
993 can be fit into 9450 9 times, resulting in a remainder of 513.
Use 9 as the next digit of our solution. 
Result so far: 67387.59
Subtract 8937 from 9450 to get 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Moving on to step 11:
993 goes into 5130 5 times with a remainder of 165.
The number 5 becomes the next digit in our result. 
Result so far: 67387.595
Subtract 4965 from 5130 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Let's proceed to step 12:
1650 divided by 993 is 1 with a remainder of 657.
Record the quotient 1 as the next digit in the result. 
Result so far: 67387.5951
The remainder is 657 after subtracting 993 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Going ahead to step 13:
The number 993 fits into 6570 6 times, leaving a remainder of 612.
Record the quotient 6 as the next digit in the result. 
Result so far: 67387.59516
Deduct 5958 from 6570 and we're left with 612.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Step 14:
993 can be fit into 6120 6 times, resulting in a remainder of 162.
The next digit of our result is 6. 
Result so far: 67387.595166
Subtracting 5958 from 6120 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

The final outcome is 67387.595166, with a leftover of 1.62e-05.
