We're dividing 640829 by 64 
We're looking to find how many times 64 goes into 640829.

Moving on to step 1:
64 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 64

Going ahead to step 2:
The number 64 fits into 64 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 64 from 64 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 64

Advancing to step 3:
When dividing 0 by 64, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 64

On to step 4:
8 divided by 64 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 8 to get 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 64

On to step 5:
82 divided by 64 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1001.0
Subtract 64 from 82 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 64

Let's proceed to step 6:
64 can be fit into 189 2 times, resulting in a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 10012.0
If we take 128 away from 189, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
If we divide 610 by 64, we get 9 and a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 10012.9
The remainder is 34 after subtracting 576 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
64 goes into 340 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10012.95
Deduct 320 from 340 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 64, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 10012.953
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
When dividing 80 by 64, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 10012.9531
If we subtract 64 from 80, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
If we divide 160 by 64, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10012.95312
The remainder is 32 after subtracting 128 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
64 can be fit into 320 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10012.953125
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 13:
64 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10012.953125
If we take 0 away from 0, we end up 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.

On to step 14:
If we divide 0 by 64, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10012.953125
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.

Our division results in 10012.953125 with a remaining 0.0.
