We look at the division of 181717 by 20 
Our goal is to divide 181717 by 20.

Going ahead to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 20

On to step 2:
The number 20 fits into 18 0 times, leaving a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 20

Step 3:
181 divided by 20 is 9 with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 180 away from 181, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Moving on to step 4:
When dividing 17 by 20, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 17, we end up with 17.
Include the next digit (1) from the dividend after 17, then repeat: 171 / 20

Going ahead to step 5:
20 goes into 171 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 908.0
The remainder is 11 after subtracting 160 from 171.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 20

Advancing to step 6:
If we divide 117 by 20, we get 5 and a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 9085.0
Deduct 100 from 117 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
20 goes into 170 8 times with a remainder of 10.
The next digit of our result is 8. 
Result so far: 9085.8
If we take 160 away from 170, we end up with 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9085.85
Subtracting 100 from 100 leaves us 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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9085.85
Subtracting 0 from 0 leaves us 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 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: 9085.85
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.

The final outcome is 9085.85, with a leftover of 0.0.
