We're dividing 640448 by 636 
We want to divide 640448 by 636.

On to step 1:
6 divided by 636 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 636

Step 2:
When dividing 64 by 636, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 636

Step 3:
636 can be fit into 640 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 636 from 640 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 636

On to step 4:
44 divided by 636 is 0 with a remainder of 44.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 44, we get 44.
Include the next digit (4) from the dividend after 44, then repeat: 444 / 636

On to step 5:
When dividing 444 by 636, we get 0 with a remainder of 444.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we subtract 0 from 444, we get 444.
Include the next digit (8) from the dividend after 444, then repeat: 4448 / 636

Step 6:
636 goes into 4448 6 times with a remainder of 632.
Put 6 as the next digit of the answer. 
Result so far: 1006.0
Deduct 3816 from 4448 and we're left with 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Going ahead to step 7:
When dividing 6320 by 636, we get 9 with a remainder of 596.
The number 9 becomes the next digit in our result. 
Result so far: 1006.9
If we take 5724 away from 6320, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

On to step 8:
The number 636 fits into 5960 9 times, leaving a remainder of 236.
Put 9 as the next digit of the answer. 
Result so far: 1006.99
The remainder is 236 after subtracting 5724 from 5960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

In conclusion, the division gives 1006.99 with a balance of 0.236.
