Let's divide 442173 by 20
We're looking to find how many times 20 goes into 442173.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 20

Going ahead to step 2:
If we divide 44 by 20, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 4 after subtracting 40 from 44.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Advancing to step 3:
The number 20 fits into 42 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 40 from 42 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Step 4:
20 can be fit into 21 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 221.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Moving on to step 5:
20 can be fit into 17 0 times, resulting in a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 2210.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 20

Moving on to step 6:
When dividing 173 by 20, we get 8 with a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 22108.0
Subtract 160 from 173 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
20 goes into 130 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 22108.6
Deduct 120 from 130 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 22108.65
The remainder is 0 after subtracting 100 from 100.
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 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: 22108.65
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.

Step 10:
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: 22108.65
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.

In conclusion, the division gives 22108.65 with a balance of 0.0.
