We look at the division of 64240352 by 999 
Let's see how many times 999 fits into 64240352.

On to step 1:
6 divided by 999 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 999

Going ahead to step 2:
64 divided by 999 is 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 999

Moving on to step 3:
642 divided by 999 is 0 with a remainder of 642.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Take the next digit (4) from the dividend and append it to 642, then repeat: 6424 / 999

Let's proceed to step 4:
999 can be fit into 6424 6 times, resulting in a remainder of 430.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 5994 from 6424, we get 430.
Grab the next digit (0) from the dividend, add it to 430, then carry on: 4300 / 999

Step 5:
999 goes into 4300 4 times with a remainder of 304.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 3996 from 4300 and we're left with 304.
Include the next digit (3) from the dividend after 304, then repeat: 3043 / 999

Step 6:
999 can be fit into 3043 3 times, resulting in a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
Subtract 2997 from 3043 to get 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 999

Advancing to step 7:
When dividing 465 by 999, we get 0 with a remainder of 465.
The next digit of our result is 0. 
Result so far: 6430.0
Deduct 0 from 465 and we're left with 465.
Grab the next digit (2) from the dividend, add it to 465, then carry on: 4652 / 999

Step 8:
999 goes into 4652 4 times with a remainder of 656.
Write down 4 as next digit of the result. 
Result so far: 64304.0
If we subtract 3996 from 4652, we get 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Moving on to step 9:
If we divide 6560 by 999, we get 6 and a remainder of 566.
The number 6 becomes the next digit in our result. 
Result so far: 64304.6
Deduct 5994 from 6560 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Advancing to step 10:
When dividing 5660 by 999, we get 5 with a remainder of 665.
The number 5 becomes the next digit in our result. 
Result so far: 64304.65
Subtracting 4995 from 5660 leaves us with 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

On to step 11:
The number 999 fits into 6650 6 times, leaving a remainder of 656.
The next digit of our result is 6. 
Result so far: 64304.656
The remainder is 656 after subtracting 5994 from 6650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Let's proceed to step 12:
999 goes into 6560 6 times with a remainder of 566.
Write down 6 as next digit of the result. 
Result so far: 64304.6566
Subtract 5994 from 6560 to get 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

After the division, we end up with 64304.6566 and a remainder of 0.00566.
