We divide 80209777 by 636
Our goal is to divide 80209777 by 636.

Advancing to step 1:
636 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 636

Let's proceed to step 2:
The number 636 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 636

Moving on to step 3:
636 can be fit into 802 1 times, resulting in a remainder of 166.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 636 from 802, we get 166.
Include the next digit (0) from the dividend after 166, then repeat: 1660 / 636

Moving on to step 4:
636 goes into 1660 2 times with a remainder of 388.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1272 from 1660 and we're left with 388.
Fetch the next digit (9) from the dividend, attach it to 388 and continue: 3889 / 636

Advancing to step 5:
3889 divided by 636 is 6 with a remainder of 73.
The next digit of our result is 6. 
Result so far: 126.0
The remainder is 73 after subtracting 3816 from 3889.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 636

Step 6:
636 can be fit into 737 1 times, resulting in a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 1261.0
Subtract 636 from 737 to get 101.
Bring next digit (7) of the dividend behind the 101 and repeat the process: 1017 / 636

On to step 7:
When dividing 1017 by 636, we get 1 with a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 12611.0
If we take 636 away from 1017, we end up with 381.
Grab the next digit (7) from the dividend, add it to 381, then carry on: 3817 / 636

On to step 8:
636 goes into 3817 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 126116.0
Subtract 3816 from 3817 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
The number 636 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 126116.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 636, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 126116.0
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 126116.0 and a remainder of 0.1.
