432162 divided by 20 
Our goal is to divide 432162 by 20.

Advancing to step 1:
4 divided by 20 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 20

Advancing to step 2:
20 can be fit into 43 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 40 from 43, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 20

Moving on to step 3:
20 can be fit into 32 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 20 from 32 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 20

On to step 4:
If we divide 121 by 20, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 216.0
If we subtract 120 from 121, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 20

Let's proceed to step 5:
16 divided by 20 is 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 2160.0
If we take 0 away from 16, we end up with 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 20

Let's proceed to step 6:
If we divide 162 by 20, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 21608.0
Subtracting 160 from 162 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 21608.1
Deduct 20 from 20 and we're left 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 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21608.1
Subtract 0 from 0 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.

On to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21608.1
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 21608.1 and a remainder of 0.0.
