We're dividing 43452 by 20 
Our goal is to divide 43452 by 20.

Step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us 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.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 40 from 43 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Moving on to step 3:
34 divided by 20 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 20 from 34, we get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 20

Moving on to step 4:
145 divided by 20 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 217.0
Deduct 140 from 145 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 20

Moving on to step 5:
The number 20 fits into 52 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 2172.0
Deduct 40 from 52 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 6:
The number 20 fits into 120 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2172.6
Subtract 120 from 120 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 7:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2172.6
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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2172.6
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 quotient of the division is 2172.6, and the remainder is 0.0.
