We look at the division of 8659936 by 20 
Let's see how many times 20 fits into 8659936.

On to step 1:
20 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

On to step 2:
20 goes into 86 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 6 after subtracting 80 from 86.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 20

Step 3:
20 goes into 65 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 60 from 65, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 20

Step 4:
20 goes into 59 2 times with a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 432.0
If we subtract 40 from 59, we get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 20

Let's proceed to step 5:
199 divided by 20 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 4329.0
Subtracting 180 from 199 leaves us with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 20

Moving on to step 6:
If we divide 193 by 20, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 43299.0
The remainder is 13 after subtracting 180 from 193.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 20

Step 7:
If we divide 136 by 20, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 432996.0
If we subtract 120 from 136, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
20 can be fit into 160 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 432996.8
Subtract 160 from 160 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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 432996.8
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 432996.8
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 432996.8, with a leftover of 0.0.
