We look at the division of 42361 by 20 
We want to divide 42361 by 20.

Let's proceed to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Let's proceed to step 2:
The number 20 fits into 42 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 40 away from 42, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

Advancing to step 3:
23 divided by 20 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 21.0
If we take 20 away from 23, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 20

Step 4:
The number 20 fits into 36 1 times, leaving a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtract 20 from 36 to get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 20

Let's proceed to step 5:
If we divide 161 by 20, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 2118.0
If we take 160 away from 161, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 2118.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 2118.05
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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2118.05
Subtract 0 from 0 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2118.05
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.

After the division, we end up with 2118.05 and a remainder of 0.0.
