We're dividing 891540 by 20 
Let's see how many times 20 fits into 891540.

Step 1:
8 divided by 20 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 20

Step 2:
The number 20 fits into 89 4 times, leaving a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 80 from 89 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 20

Let's proceed to step 3:
The number 20 fits into 91 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 80 from 91, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Advancing to step 4:
115 divided by 20 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 445.0
Deduct 100 from 115 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 20

Let's proceed to step 5:
20 can be fit into 154 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 4457.0
Deduct 140 from 154 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 20

Let's proceed to step 6:
20 can be fit into 140 7 times, resulting in a remainder of 0.
The next digit of our result is 7. 
Result so far: 44577.0
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.

Going ahead to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 44577.0
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.

Going ahead to step 8:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 44577.0
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.

In conclusion, the division gives 44577.0 with a balance of 0.0.
