We're dividing 857444 by 20 
We're looking to find how many times 20 goes into 857444.

Step 1:
20 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 20

Let's proceed to step 2:
When dividing 85 by 20, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 80 from 85 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 20

Going ahead to step 3:
20 can be fit into 57 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 17 after subtracting 40 from 57.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 20

Moving on to step 4:
20 goes into 174 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 428.0
Subtract 160 from 174 to get 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 20

Moving on to step 5:
20 can be fit into 144 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 4287.0
Subtracting 140 from 144 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 20

On to step 6:
If we divide 44 by 20, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 42872.0
Subtract 40 from 44 to 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.

On to step 7:
If we divide 40 by 20, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 42872.2
Subtract 40 from 40 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.

Step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 42872.2
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 42872.2
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.

After the division, we end up with 42872.2 and a remainder of 0.0.
