We look at the division of 470321 by 20 
We're looking to find how many times 20 goes into 470321.

Advancing to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Advancing to step 2:
20 goes into 47 2 times with a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 40 from 47 leaves us with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 20

On to step 3:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 60 away from 70, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 20

Let's proceed to step 4:
20 can be fit into 103 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 235.0
Subtract 100 from 103 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 20

Advancing to step 5:
If we divide 32 by 20, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 2351.0
Subtracting 20 from 32 leaves us with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 20

On to step 6:
20 can be fit into 121 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 23516.0
If we take 120 away from 121, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
10 divided by 20 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 23516.0
If we subtract 0 from 10, we 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 8:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 23516.05
If we subtract 100 from 100, 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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23516.05
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.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 23516.05
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.

After the division, we end up with 23516.05 and a remainder of 0.0.
