66608984 ÷ 999 
Let's see how many times 999 fits into 66608984.

On to step 1:
When dividing 6 by 999, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 999

Let's proceed to step 2:
66 divided by 999 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 999

Step 3:
666 divided by 999 is 0 with a remainder of 666.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 666 after subtracting 0 from 666.
Grab the next digit (0) from the dividend, add it to 666, then carry on: 6660 / 999

Let's proceed to step 4:
If we divide 6660 by 999, we get 6 and a remainder of 666.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 5994 from 6660, we get 666.
Include the next digit (8) from the dividend after 666, then repeat: 6668 / 999

Advancing to step 5:
999 can be fit into 6668 6 times, resulting in a remainder of 674.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
If we take 5994 away from 6668, we end up with 674.
Grab the next digit (9) from the dividend, add it to 674, then carry on: 6749 / 999

Advancing to step 6:
The number 999 fits into 6749 6 times, leaving a remainder of 755.
Put 6 as the next digit of the answer. 
Result so far: 666.0
Subtract 5994 from 6749 to get 755.
Bring next digit (8) of the dividend behind the 755 and repeat the process: 7558 / 999

Step 7:
7558 divided by 999 is 7 with a remainder of 565.
Record the quotient 7 as the next digit in the result. 
Result so far: 6667.0
The remainder is 565 after subtracting 6993 from 7558.
Take the next digit (4) from the dividend and append it to 565, then repeat: 5654 / 999

Going ahead to step 8:
999 goes into 5654 5 times with a remainder of 659.
The next digit of our result is 5. 
Result so far: 66675.0
The remainder is 659 after subtracting 4995 from 5654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

On to step 9:
The number 999 fits into 6590 6 times, leaving a remainder of 596.
The next digit of our result is 6. 
Result so far: 66675.6
Subtracting 5994 from 6590 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Step 10:
999 goes into 5960 5 times with a remainder of 965.
Put 5 as the next digit of the answer. 
Result so far: 66675.65
Subtracting 4995 from 5960 leaves us with 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Let's proceed to step 11:
When dividing 9650 by 999, we get 9 with a remainder of 659.
The number 9 becomes the next digit in our result. 
Result so far: 66675.659
If we subtract 8991 from 9650, we get 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Going ahead to step 12:
When dividing 6590 by 999, we get 6 with a remainder of 596.
Put 6 as the next digit of the answer. 
Result so far: 66675.6596
If we subtract 5994 from 6590, we get 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 13:
If we divide 5960 by 999, we get 5 and a remainder of 965.
Put 5 as the next digit of the answer. 
Result so far: 66675.65965
Deduct 4995 from 5960 and we're left with 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Moving on to step 14:
When dividing 9650 by 999, we get 9 with a remainder of 659.
Write down 9 as next digit of the result. 
Result so far: 66675.659659
If we take 8991 away from 9650, we end up with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Advancing to step 15:
If we divide 6590 by 999, we get 6 and a remainder of 596.
Use 6 as the next digit of our solution. 
Result so far: 66675.6596596
Subtracting 5994 from 6590 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 16:
999 goes into 5960 5 times with a remainder of 965.
Write down 5 as next digit of the result. 
Result so far: 66675.65965965
If we subtract 4995 from 5960, we get 965.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9650, and continue the process.

Our division results in 66675.65965965 with a remaining 9.65e-07.
