We look at the division of 64575220 by 999 
Let's see how many times 999 fits into 64575220.

On to step 1:
999 goes into 6 0 times 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.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 999

Step 2:
The number 999 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 999

Moving on to step 3:
The number 999 fits into 645 0 times, leaving a remainder of 645.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 645, we get 645.
Include the next digit (7) from the dividend after 645, then repeat: 6457 / 999

On to step 4:
When dividing 6457 by 999, we get 6 with a remainder of 463.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 5994 away from 6457, we end up with 463.
Bring next digit (5) of the dividend behind the 463 and repeat the process: 4635 / 999

Let's proceed to step 5:
999 goes into 4635 4 times with a remainder of 639.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Deduct 3996 from 4635 and we're left with 639.
Include the next digit (2) from the dividend after 639, then repeat: 6392 / 999

Moving on to step 6:
When dividing 6392 by 999, we get 6 with a remainder of 398.
Put 6 as the next digit of the answer. 
Result so far: 646.0
The remainder is 398 after subtracting 5994 from 6392.
Grab the next digit (2) from the dividend, add it to 398, then carry on: 3982 / 999

Moving on to step 7:
999 can be fit into 3982 3 times, resulting in a remainder of 985.
The next digit of our result is 3. 
Result so far: 6463.0
If we take 2997 away from 3982, we end up with 985.
Fetch the next digit (0) from the dividend, attach it to 985 and continue: 9850 / 999

Let's proceed to step 8:
When dividing 9850 by 999, we get 9 with a remainder of 859.
Record the quotient 9 as the next digit in the result. 
Result so far: 64639.0
Deduct 8991 from 9850 and we're left with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Step 9:
When dividing 8590 by 999, we get 8 with a remainder of 598.
Record the quotient 8 as the next digit in the result. 
Result so far: 64639.8
Deduct 7992 from 8590 and we're left with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Advancing to step 10:
999 goes into 5980 5 times with a remainder of 985.
Use 5 as the next digit of our solution. 
Result so far: 64639.85
Deduct 4995 from 5980 and we're left with 985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9850, and continue the process.

On to step 11:
999 goes into 9850 9 times with a remainder of 859.
Write down 9 as next digit of the result. 
Result so far: 64639.859
Subtracting 8991 from 9850 leaves us with 859.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Step 12:
8590 divided by 999 is 8 with a remainder of 598.
Write down 8 as next digit of the result. 
Result so far: 64639.8598
Subtract 7992 from 8590 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Let's proceed to step 13:
999 goes into 5980 5 times with a remainder of 985.
The number 5 becomes the next digit in our result. 
Result so far: 64639.85985
Subtract 4995 from 5980 to get 985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9850, and continue the process.

Step 14:
9850 divided by 999 is 9 with a remainder of 859.
Put 9 as the next digit of the answer. 
Result so far: 64639.859859
The remainder is 859 after subtracting 8991 from 9850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8590, and continue the process.

Advancing to step 15:
8590 divided by 999 is 8 with a remainder of 598.
Record the quotient 8 as the next digit in the result. 
Result so far: 64639.8598598
If we take 7992 away from 8590, we end up with 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Step 16:
999 goes into 5980 5 times with a remainder of 985.
The next digit of our result is 5. 
Result so far: 64639.85985985
If we take 4995 away from 5980, we end up with 985.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9850, and continue the process.

The final result is 64639.85985985 with a remainder of 9.85e-07.
