We look at the division of 183591 by 20 
We're looking to find how many times 20 goes into 183591.

Going ahead to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

Let's proceed to step 2:
20 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 20

Step 3:
20 goes into 183 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 180 from 183 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 20

Moving on to step 4:
20 goes into 35 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
The remainder is 15 after subtracting 20 from 35.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 20

Moving on to step 5:
When dividing 159 by 20, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Subtracting 140 from 159 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 20

Step 6:
20 goes into 191 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 9179.0
Subtracting 180 from 191 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
110 divided by 20 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9179.5
Subtract 100 from 110 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:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9179.55
The remainder is 0 after subtracting 100 from 100.
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 9179.55 with a balance of 0.0.
