We look at the division of 821854 by 20 
We're looking to find how many times 20 goes into 821854.

Moving on to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 20

Step 2:
The number 20 fits into 82 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 80 from 82 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 20

Advancing to step 3:
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: 41.0
If we subtract 20 from 21, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 20

On to step 4:
20 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 410.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 20

Let's proceed to step 5:
20 can be fit into 185 9 times, resulting in a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 4109.0
Subtracting 180 from 185 leaves us with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 20

On to step 6:
20 goes into 54 2 times with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 41092.0
Subtracting 40 from 54 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 20 fits into 140 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 41092.7
If we subtract 140 from 140, 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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41092.7
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41092.7
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 41092.7, and the remainder is 0.0.
