We're dividing 168807 by 20 
We want to divide 168807 by 20.

On to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 20

On to step 2:
16 divided by 20 is 0 with 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.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 20

Let's proceed to step 3:
20 can be fit into 168 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 160 from 168 leaves us with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 20

Advancing to step 4:
The number 20 fits into 88 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 8 after subtracting 80 from 88.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

Let's proceed to step 5:
20 goes into 80 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 844.0
If we subtract 80 from 80, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 20

Advancing to step 6:
20 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 8440.0
If we take 0 away from 7, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 20, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 8440.3
Subtracting 60 from 70 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.

Advancing to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8440.35
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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8440.35
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.

On to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8440.35
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.

The final outcome is 8440.35, with a leftover of 0.0.
