Let's divide 8405520 by 636
We want to divide 8405520 by 636.

Let's proceed to step 1:
8 divided by 636 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 636

Going ahead to step 2:
636 can be fit into 84 0 times, resulting in a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 84, we get 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 636

Advancing to step 3:
636 can be fit into 840 1 times, resulting in a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 204 after subtracting 636 from 840.
Bring next digit (5) of the dividend behind the 204 and repeat the process: 2045 / 636

Let's proceed to step 4:
2045 divided by 636 is 3 with a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 1908 from 2045, we get 137.
Bring next digit (5) of the dividend behind the 137 and repeat the process: 1375 / 636

Let's proceed to step 5:
636 can be fit into 1375 2 times, resulting in a remainder of 103.
The next digit of our result is 2. 
Result so far: 132.0
Subtracting 1272 from 1375 leaves us with 103.
Take the next digit (2) from the dividend and append it to 103, then repeat: 1032 / 636

Going ahead to step 6:
636 can be fit into 1032 1 times, resulting in a remainder of 396.
Use 1 as the next digit of our solution. 
Result so far: 1321.0
If we subtract 636 from 1032, we get 396.
Grab the next digit (0) from the dividend, add it to 396, then carry on: 3960 / 636

On to step 7:
3960 divided by 636 is 6 with a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 13216.0
If we take 3816 away from 3960, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Going ahead to step 8:
636 can be fit into 1440 2 times, resulting in a remainder of 168.
Use 2 as the next digit of our solution. 
Result so far: 13216.2
Subtracting 1272 from 1440 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 9:
When dividing 1680 by 636, we get 2 with a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 13216.22
Subtract 1272 from 1680 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

After the division, we end up with 13216.22 and a remainder of 0.408.
