43507728 divided by 20 
Our goal is to divide 43507728 by 20.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in 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.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Advancing to step 2:
20 goes into 43 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 43 leaves us with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 20

On to step 3:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 20 away from 35, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 20

Step 4:
When dividing 150 by 20, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 217.0
Subtracting 140 from 150 leaves us with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 20

Let's proceed to step 5:
When dividing 107 by 20, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 2175.0
If we take 100 away from 107, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 20

Moving on to step 6:
77 divided by 20 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 21753.0
If we take 60 away from 77, we end up with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 20

On to step 7:
When dividing 172 by 20, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 217538.0
Subtract 160 from 172 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 20

Moving on to step 8:
20 goes into 128 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 2175386.0
Subtracting 120 from 128 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 20, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2175386.4
If we subtract 80 from 80, 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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2175386.4
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.

Going ahead to step 11:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2175386.4
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.

The final outcome is 2175386.4, with a leftover of 0.0.
