163169 ÷ 20 
Let's see how many times 20 fits into 163169.

Step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 20

On to step 2:
When dividing 16 by 20, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 20

Let's proceed to step 3:
The number 20 fits into 163 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 160 from 163 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

On to step 4:
When dividing 31 by 20, we get 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we subtract 20 from 31, we get 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 20

Advancing to step 5:
If we divide 116 by 20, we get 5 and a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 815.0
Subtract 100 from 116 to get 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 20

On to step 6:
If we divide 169 by 20, we get 8 and a remainder of 9.
The next digit of our result is 8. 
Result so far: 8158.0
Subtract 160 from 169 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 20, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 8158.4
Subtracting 80 from 90 leaves us 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.

On 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: 8158.45
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8158.45
The remainder is 0 after subtracting 0 from 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8158.45
If we subtract 0 from 0, 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.

The quotient of the division is 8158.45, and the remainder is 0.0.
