We divide 640896 by 64
Our goal is to divide 640896 by 64.

Advancing to step 1:
64 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
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 64

On to step 2:
64 goes into 64 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 64 away from 64, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 64

On to step 3:
64 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 64

On to step 4:
8 divided by 64 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 64

Advancing to step 5:
If we divide 89 by 64, we get 1 and a remainder of 25.
The next digit of our result is 1. 
Result so far: 1001.0
Subtract 64 from 89 to get 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 64

On to step 6:
64 goes into 256 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 10014.0
The remainder is 0 after subtracting 256 from 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
0 divided by 64 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10014.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 64 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10014.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 10014.0 with a remaining 0.0.
