Let's divide 424131 by 20
We're looking to find how many times 20 goes into 424131.

Step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Moving on to step 2:
If we divide 42 by 20, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 42 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 20

On to step 3:
20 can be fit into 24 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 20 away from 24, we end up with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 20

Let's proceed to step 4:
The number 20 fits into 41 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 212.0
The remainder is 1 after subtracting 40 from 41.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Let's proceed to step 5:
When dividing 13 by 20, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 2120.0
If we take 0 away from 13, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 20

Step 6:
If we divide 131 by 20, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 21206.0
If we subtract 120 from 131, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
If we divide 110 by 20, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 21206.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21206.55
If we subtract 100 from 100, 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 21206.55 with a remainder of 0.0.
