We're dividing 104355 by 20 
Let's see how many times 20 fits into 104355.

On to step 1:
20 goes into 1 0 times 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.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 20

Moving on to step 2:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 20

On to step 3:
104 divided by 20 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 4 after subtracting 100 from 104.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 20

Going ahead to step 4:
The number 20 fits into 43 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 52.0
Subtract 40 from 43 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

On to step 5:
If we divide 35 by 20, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 521.0
Subtract 20 from 35 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

On to step 6:
20 can be fit into 155 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 5217.0
The remainder is 15 after subtracting 140 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
20 goes into 150 7 times with a remainder of 10.
The next digit of our result is 7. 
Result so far: 5217.7
Subtract 140 from 150 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.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5217.75
If we take 100 away from 100, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5217.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5217.75
The remainder is 0 after subtracting 0 from 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 final outcome is 5217.75, with a leftover of 0.0.
