6680691 ÷ 999 
We want to divide 6680691 by 999.

Going ahead to step 1:
If we divide 6 by 999, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 999

Let's proceed to step 2:
When dividing 66 by 999, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 999

Advancing to step 3:
The number 999 fits into 668 0 times, leaving a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 668, we get 668.
Fetch the next digit (0) from the dividend, attach it to 668 and continue: 6680 / 999

Going ahead to step 4:
999 goes into 6680 6 times with a remainder of 686.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 5994 from 6680 leaves us with 686.
Bring next digit (6) of the dividend behind the 686 and repeat the process: 6866 / 999

Going ahead to step 5:
When dividing 6866 by 999, we get 6 with a remainder of 872.
Put 6 as the next digit of the answer. 
Result so far: 66.0
The remainder is 872 after subtracting 5994 from 6866.
Fetch the next digit (9) from the dividend, attach it to 872 and continue: 8729 / 999

Let's proceed to step 6:
If we divide 8729 by 999, we get 8 and a remainder of 737.
The next digit of our result is 8. 
Result so far: 668.0
If we take 7992 away from 8729, we end up with 737.
Take the next digit (1) from the dividend and append it to 737, then repeat: 7371 / 999

Step 7:
999 can be fit into 7371 7 times, resulting in a remainder of 378.
Put 7 as the next digit of the answer. 
Result so far: 6687.0
Deduct 6993 from 7371 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 8:
If we divide 3780 by 999, we get 3 and a remainder of 783.
Record the quotient 3 as the next digit in the result. 
Result so far: 6687.3
Subtract 2997 from 3780 to get 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Step 9:
If we divide 7830 by 999, we get 7 and a remainder of 837.
Write down 7 as next digit of the result. 
Result so far: 6687.37
The remainder is 837 after subtracting 6993 from 7830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Advancing to step 10:
The number 999 fits into 8370 8 times, leaving a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 6687.378
The remainder is 378 after subtracting 7992 from 8370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 11:
999 can be fit into 3780 3 times, resulting in a remainder of 783.
Use 3 as the next digit of our solution. 
Result so far: 6687.3783
Subtracting 2997 from 3780 leaves us with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Let's proceed to step 12:
999 can be fit into 7830 7 times, resulting in a remainder of 837.
Put 7 as the next digit of the answer. 
Result so far: 6687.37837
If we take 6993 away from 7830, we end up with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Step 13:
8370 divided by 999 is 8 with a remainder of 378.
Write down 8 as next digit of the result. 
Result so far: 6687.378378
Deduct 7992 from 8370 and we're left with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Step 14:
3780 divided by 999 is 3 with a remainder of 783.
Write down 3 as next digit of the result. 
Result so far: 6687.3783783
If we take 2997 away from 3780, we end up with 783.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7830, and continue the process.

Let's proceed to step 15:
999 can be fit into 7830 7 times, resulting in a remainder of 837.
Put 7 as the next digit of the answer. 
Result so far: 6687.37837837
Subtracting 6993 from 7830 leaves us with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

After the division, we end up with 6687.37837837 and a remainder of 8.37e-07.
