591438 ÷ 20 
We want to divide 591438 by 20.

Going ahead to step 1:
20 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 20

Advancing to step 2:
When dividing 59 by 20, we get 2 with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 59 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 20

Let's proceed to step 3:
20 can be fit into 191 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 180 from 191, we get 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 20

Let's proceed to step 4:
When dividing 114 by 20, we get 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 295.0
If we subtract 100 from 114, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

Going ahead to step 5:
If we divide 143 by 20, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 2957.0
If we take 140 away from 143, we end up with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Advancing to step 6:
20 goes into 38 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 29571.0
Subtract 20 from 38 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 29571.9
If we subtract 180 from 180, 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29571.9
If we subtract 0 from 0, 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 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29571.9
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.

In conclusion, the division gives 29571.9 with a balance of 0.0.
