432339 divided by 20 
Our goal is to divide 432339 by 20.

Moving on to step 1:
20 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 20

Advancing to step 2:
When dividing 43 by 20, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 43, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 20

Going ahead to step 3:
32 divided by 20 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 20 from 32, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 20

Going ahead to step 4:
The number 20 fits into 123 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 216.0
Subtracting 120 from 123 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 20

Advancing to step 5:
33 divided by 20 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 2161.0
Subtract 20 from 33 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 20

Let's proceed to step 6:
The number 20 fits into 139 6 times, leaving a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 21616.0
If we subtract 120 from 139, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
The next digit of our result is 9. 
Result so far: 21616.9
Deduct 180 from 190 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21616.95
Subtracting 100 from 100 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21616.95
If we take 0 away from 0, 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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21616.95
Deduct 0 from 0 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.

The quotient of the division is 21616.95, and the remainder is 0.0.
