We divide 42364 by 20
We're looking to find how many times 20 goes into 42364.

Going ahead to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

Step 2:
When dividing 42 by 20, we get 2 with a remainder of 2.
Record the quotient 2 as the next digit in the 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

On to step 3:
If we divide 23 by 20, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 20 from 23 to get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 20

Step 4:
20 goes into 36 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 211.0
Subtracting 20 from 36 leaves us with 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 20

Moving on to step 5:
When dividing 164 by 20, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 2118.0
If we subtract 160 from 164, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2118.2
If we take 40 away from 40, 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.

Advancing to step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2118.2
Deduct 0 from 0 and we're left 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2118.2
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.

Our division results in 2118.2 with a remaining 0.0.
