80358676 divided by 636 
We want to figure out the number of times 80358676 can be divided by 636.

On to step 1:
When dividing 8 by 636, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 636

Going ahead to step 2:
636 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 636

On to step 3:
636 can be fit into 803 1 times, resulting in a remainder of 167.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 636 from 803, we get 167.
Take the next digit (5) from the dividend and append it to 167, then repeat: 1675 / 636

Going ahead to step 4:
When dividing 1675 by 636, we get 2 with a remainder of 403.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 1272 from 1675 leaves us with 403.
Include the next digit (8) from the dividend after 403, then repeat: 4038 / 636

Step 5:
When dividing 4038 by 636, we get 6 with a remainder of 222.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 3816 away from 4038, we end up with 222.
Append the next digit (6) from the dividend to 222 and continue with: 2226 / 636

Step 6:
636 goes into 2226 3 times with a remainder of 318.
Put 3 as the next digit of the answer. 
Result so far: 1263.0
If we subtract 1908 from 2226, we get 318.
Include the next digit (7) from the dividend after 318, then repeat: 3187 / 636

Advancing to step 7:
If we divide 3187 by 636, we get 5 and a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 12635.0
Subtracting 3180 from 3187 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 636

Moving on to step 8:
When dividing 76 by 636, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 126350.0
If we take 0 away from 76, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
760 divided by 636 is 1 with a remainder of 124.
The number 1 becomes the next digit in our result. 
Result so far: 126350.1
Subtract 636 from 760 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 10:
If we divide 1240 by 636, we get 1 and a remainder of 604.
The number 1 becomes the next digit in our result. 
Result so far: 126350.11
Subtracting 636 from 1240 leaves us with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

The final result is 126350.11 with a remainder of 0.604.
