We divide 163193 by 20
We want to figure out the number of times 163193 can be divided by 20.

On to step 1:
20 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 20

On to step 2:
20 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 20

Advancing to step 3:
If we divide 163 by 20, we get 8 and a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 3 after subtracting 160 from 163.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Step 4:
The number 20 fits into 31 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we subtract 20 from 31, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 20

On to step 5:
The number 20 fits into 119 5 times, leaving a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 815.0
If we subtract 100 from 119, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 20

Moving on to step 6:
If we divide 193 by 20, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 8159.0
If we subtract 180 from 193, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 8159.6
Deduct 120 from 130 and we're left 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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8159.65
Subtract 100 from 100 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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8159.65
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8159.65
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.

After the division, we end up with 8159.65 and a remainder of 0.0.
