We look at the division of 850884 by 20 
Let's see how many times 20 fits into 850884.

Step 1:
20 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 20

On to step 2:
85 divided by 20 is 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 80 from 85 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 20

On to step 3:
If we divide 50 by 20, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 42.0
Deduct 40 from 50 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 20

Moving on to step 4:
When dividing 108 by 20, we get 5 with a remainder of 8.
The next digit of our result is 5. 
Result so far: 425.0
If we take 100 away from 108, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 20

Let's proceed to step 5:
20 goes into 88 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4254.0
The remainder is 8 after subtracting 80 from 88.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Step 6:
The number 20 fits into 84 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 42544.0
The remainder is 4 after subtracting 80 from 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 42544.2
If we subtract 40 from 40, 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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42544.2
If we take 0 away from 0, 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42544.2
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.

The quotient of the division is 42544.2, and the remainder is 0.0.
