172197 divided by 20 
We want to figure out the number of times 172197 can be divided by 20.

On to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Step 2:
If we divide 17 by 20, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 20

Step 3:
20 goes into 172 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 160 from 172, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 20

Let's proceed to step 4:
121 divided by 20 is 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 120 away from 121, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

Going ahead to step 5:
19 divided by 20 is 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 860.0
The remainder is 19 after subtracting 0 from 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 20

Moving on to step 6:
20 can be fit into 197 9 times, resulting in a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 8609.0
If we subtract 180 from 197, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
The number 20 fits into 170 8 times, leaving a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 8609.8
If we subtract 160 from 170, we 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.

Let's proceed to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 8609.85
If we subtract 100 from 100, 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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8609.85
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.

Moving on to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8609.85
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 quotient of the division is 8609.85, and the remainder is 0.0.
