942551 ÷ 20 
Our goal is to divide 942551 by 20.

Let's proceed to step 1:
9 divided by 20 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 20

Let's proceed to step 2:
When dividing 94 by 20, we get 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 80 from 94 and we're left with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 20

Step 3:
142 divided by 20 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtracting 140 from 142 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 20

Moving on to step 4:
When dividing 25 by 20, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 471.0
The remainder is 5 after subtracting 20 from 25.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 20

Moving on to step 5:
20 goes into 55 2 times with a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 4712.0
If we take 40 away from 55, we end up with 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 20

Step 6:
20 goes into 151 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 47127.0
Deduct 140 from 151 and we're left with 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:
20 goes into 110 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 47127.5
If we subtract 100 from 110, we 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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 47127.55
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.

Our division results in 47127.55 with a remaining 0.0.
