We're dividing 217583 by 20 
We want to figure out the number of times 217583 can be divided by 20.

Let's proceed to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 20

Let's proceed to step 2:
20 goes into 21 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 1 after subtracting 20 from 21.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 20

Step 3:
17 divided by 20 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Let's proceed to step 4:
When dividing 175 by 20, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 15 after subtracting 160 from 175.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 20

Let's proceed to step 5:
20 can be fit into 158 7 times, resulting in a remainder of 18.
The next digit of our result is 7. 
Result so far: 1087.0
Deduct 140 from 158 and we're left with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 20

Let's proceed to step 6:
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: 10879.0
If we subtract 180 from 183, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 10879.1
Subtract 20 from 30 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10879.15
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10879.15
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.

Step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10879.15
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 10879.15 with a remainder of 0.0.
