66246368 divided by 999 
Let's see how many times 999 fits into 66246368.

Step 1:
6 divided by 999 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 999

Moving on to step 2:
66 divided by 999 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 999

On to step 3:
If we divide 662 by 999, we get 0 and a remainder of 662.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 662 after subtracting 0 from 662.
Include the next digit (4) from the dividend after 662, then repeat: 6624 / 999

Let's proceed to step 4:
When dividing 6624 by 999, we get 6 with a remainder of 630.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 630 after subtracting 5994 from 6624.
Bring next digit (6) of the dividend behind the 630 and repeat the process: 6306 / 999

Moving on to step 5:
6306 divided by 999 is 6 with a remainder of 312.
Use 6 as the next digit of our solution. 
Result so far: 66.0
Subtracting 5994 from 6306 leaves us with 312.
Append the next digit (3) from the dividend to 312 and continue with: 3123 / 999

Let's proceed to step 6:
When dividing 3123 by 999, we get 3 with a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 663.0
If we take 2997 away from 3123, we end up with 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 999

Step 7:
When dividing 1266 by 999, we get 1 with a remainder of 267.
Write down 1 as next digit of the result. 
Result so far: 6631.0
Subtracting 999 from 1266 leaves us with 267.
Take the next digit (8) from the dividend and append it to 267, then repeat: 2678 / 999

Step 8:
999 can be fit into 2678 2 times, resulting in a remainder of 680.
Put 2 as the next digit of the answer. 
Result so far: 66312.0
The remainder is 680 after subtracting 1998 from 2678.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 9:
The number 999 fits into 6800 6 times, leaving a remainder of 806.
The number 6 becomes the next digit in our result. 
Result so far: 66312.6
Deduct 5994 from 6800 and we're left with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Going ahead to step 10:
8060 divided by 999 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 66312.68
The remainder is 68 after subtracting 7992 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 11:
680 divided by 999 is 0 with a remainder of 680.
Use 0 as the next digit of our solution. 
Result so far: 66312.68
If we subtract 0 from 680, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Advancing to step 12:
If we divide 6800 by 999, we get 6 and a remainder of 806.
The number 6 becomes the next digit in our result. 
Result so far: 66312.6806
If we take 5994 away from 6800, we end up with 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Let's proceed to step 13:
999 can be fit into 8060 8 times, resulting in a remainder of 68.
The next digit of our result is 8. 
Result so far: 66312.68068
The remainder is 68 after subtracting 7992 from 8060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
999 can be fit into 680 0 times, resulting in a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 66312.68068
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 15:
999 can be fit into 6800 6 times, resulting in a remainder of 806.
Put 6 as the next digit of the answer. 
Result so far: 66312.6806806
Subtract 5994 from 6800 to get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Let's proceed to step 16:
999 can be fit into 8060 8 times, resulting in a remainder of 68.
Put 8 as the next digit of the answer. 
Result so far: 66312.68068068
If we take 7992 away from 8060, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

After the division, we end up with 66312.68068068 and a remainder of 6.8e-08.
