We divide 104511 by 20
We're looking to find how many times 20 goes into 104511.

On to step 1:
1 divided by 20 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 20

Step 2:
20 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 20

Going ahead to step 3:
When dividing 104 by 20, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 100 from 104 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Advancing to step 4:
20 can be fit into 45 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 40 away from 45, we end up with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Step 5:
20 can be fit into 51 2 times, resulting in a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 522.0
If we subtract 40 from 51, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 20

Going ahead to step 6:
When dividing 111 by 20, we get 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 5225.0
If we subtract 100 from 111, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 5225.5
Deduct 100 from 110 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5225.55
Subtract 100 from 100 to 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.

The quotient of the division is 5225.55, and the remainder is 0.0.
