We're dividing 581400 by 20 
We want to figure out the number of times 581400 can be divided by 20.

Going ahead to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Let's proceed to step 2:
20 can be fit into 58 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 58, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

On to step 3:
If we divide 181 by 20, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Deduct 180 from 181 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 20

Let's proceed to step 4:
The number 20 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
Subtract 0 from 14 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 20

Advancing to step 5:
20 goes into 140 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 2907.0
If we subtract 140 from 140, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 20

Going ahead to step 6:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29070.0
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.

Step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29070.0
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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29070.0
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.

The final outcome is 29070.0, with a leftover of 0.0.
