Let's divide 429553 by 20
Our goal is to divide 429553 by 20.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Step 2:
20 can be fit into 42 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 42 to get 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

On to step 3:
The number 20 fits into 29 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 20 from 29 to get 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 20

Let's proceed to step 4:
If we divide 95 by 20, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 214.0
Deduct 80 from 95 and we're left with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

Advancing to step 5:
20 can be fit into 155 7 times, resulting in a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 2147.0
Subtracting 140 from 155 leaves us with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 20

Step 6:
20 goes into 153 7 times with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 21477.0
Subtracting 140 from 153 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
130 divided by 20 is 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 21477.6
If we take 120 away from 130, we end up 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21477.65
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.
Use 0 as the next digit of our solution. 
Result so far: 21477.65
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.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21477.65
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.

The final result is 21477.65 with a remainder of 0.0.
