We look at the division of 430769 by 20 
Let's see how many times 20 fits into 430769.

Going ahead to step 1:
20 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

On 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
The remainder is 3 after subtracting 40 from 43.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 20

Advancing to step 3:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 20 from 30 leaves us with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 20

On to step 4:
When dividing 107 by 20, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 215.0
Subtract 100 from 107 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 20

On to step 5:
If we divide 76 by 20, we get 3 and a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 2153.0
If we take 60 away from 76, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 20

On to step 6:
20 goes into 169 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 21538.0
Subtract 160 from 169 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.

Going ahead to step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 21538.4
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.

On 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: 21538.45
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21538.45
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21538.45
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.

In conclusion, the division gives 21538.45 with a balance of 0.0.
