475903 ÷ 20 
We want to figure out the number of times 475903 can be divided by 20.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 20

Moving on to step 2:
20 can be fit into 47 2 times, resulting in a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 40 from 47, we get 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 20

Moving on to step 3:
The number 20 fits into 75 3 times, leaving a remainder of 15.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 60 from 75 and we're left with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

Going ahead to step 4:
20 can be fit into 159 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 237.0
If we subtract 140 from 159, we get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 20

Moving on to step 5:
190 divided by 20 is 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 2379.0
If we take 180 away from 190, we end up with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 20

Moving on to step 6:
The number 20 fits into 103 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 23795.0
Deduct 100 from 103 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 23795.1
If we take 20 away from 30, we end up 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.

Advancing to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 23795.15
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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23795.15
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.

Going ahead to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23795.15
If we subtract 0 from 0, we 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.

In conclusion, the division gives 23795.15 with a balance of 0.0.
