We look at the division of 64407885 by 996 
Our goal is to divide 64407885 by 996.

Let's proceed to step 1:
996 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 996

Advancing to step 2:
When dividing 64 by 996, we get 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 996

Let's proceed to step 3:
When dividing 644 by 996, we get 0 with a remainder of 644.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 644 to get 644.
Bring next digit (0) of the dividend behind the 644 and repeat the process: 6440 / 996

Advancing to step 4:
6440 divided by 996 is 6 with a remainder of 464.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5976 from 6440 and we're left with 464.
Append the next digit (7) from the dividend to 464 and continue with: 4647 / 996

Moving on to step 5:
The number 996 fits into 4647 4 times, leaving a remainder of 663.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
The remainder is 663 after subtracting 3984 from 4647.
Include the next digit (8) from the dividend after 663, then repeat: 6638 / 996

Moving on to step 6:
The number 996 fits into 6638 6 times, leaving a remainder of 662.
Record the quotient 6 as the next digit in the result. 
Result so far: 646.0
Subtracting 5976 from 6638 leaves us with 662.
Grab the next digit (8) from the dividend, add it to 662, then carry on: 6628 / 996

Going ahead to step 7:
If we divide 6628 by 996, we get 6 and a remainder of 652.
The next digit of our result is 6. 
Result so far: 6466.0
If we take 5976 away from 6628, we end up with 652.
Bring next digit (5) of the dividend behind the 652 and repeat the process: 6525 / 996

Going ahead to step 8:
If we divide 6525 by 996, we get 6 and a remainder of 549.
The number 6 becomes the next digit in our result. 
Result so far: 64666.0
Subtract 5976 from 6525 to get 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Advancing to step 9:
When dividing 5490 by 996, we get 5 with a remainder of 510.
Put 5 as the next digit of the answer. 
Result so far: 64666.5
If we subtract 4980 from 5490, we get 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Going ahead to step 10:
The number 996 fits into 5100 5 times, leaving a remainder of 120.
The next digit of our result is 5. 
Result so far: 64666.55
Deduct 4980 from 5100 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 64666.55 and a remainder of 0.12.
