432949 divided by 20 
We're looking to find how many times 20 goes into 432949.

Going ahead to step 1:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 20

Advancing to step 2:
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: 2.0
Subtracting 40 from 43 leaves us with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 20

Step 3:
20 goes into 32 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtracting 20 from 32 leaves us with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 20

Step 4:
If we divide 129 by 20, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
Deduct 120 from 129 and we're left with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 20

On to step 5:
The number 20 fits into 94 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 2164.0
Deduct 80 from 94 and we're left with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 20

Moving on to step 6:
149 divided by 20 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 21647.0
Subtract 140 from 149 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
90 divided by 20 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 21647.4
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 21647.45
Subtract 100 from 100 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.

Let's proceed 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: 21647.45
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:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21647.45
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.

Our division results in 21647.45 with a remaining 0.0.
