We divide 856181 by 20
We want to divide 856181 by 20.

Advancing to step 1:
20 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
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

Moving on to step 2:
20 goes into 85 4 times with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 5 after subtracting 80 from 85.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 20

Moving on to step 3:
If we divide 56 by 20, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
If we subtract 40 from 56, we get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 20

Advancing to step 4:
The number 20 fits into 161 8 times, leaving a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 428.0
Subtracting 160 from 161 leaves us with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 20

Advancing to step 5:
When dividing 18 by 20, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 4280.0
Subtract 0 from 18 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 20

Advancing to step 6:
20 can be fit into 181 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 42809.0
If we take 180 away from 181, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 20, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 42809.0
Subtract 0 from 10 to 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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 42809.05
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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42809.05
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 42809.05
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.

The final result is 42809.05 with a remainder of 0.0.
