128659 divided by 20 
We're looking to find how many times 20 goes into 128659.

Going ahead to step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 20

Let's proceed to step 2:
20 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 20

On to step 3:
128 divided by 20 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
If we take 120 away from 128, we end up with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 20

Advancing to step 4:
When dividing 86 by 20, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 80 from 86, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 20

Moving on to step 5:
20 can be fit into 65 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 643.0
Deduct 60 from 65 and we're left with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 20

On to step 6:
20 can be fit into 59 2 times, resulting in a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 6432.0
If we take 40 away from 59, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 20, we get 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 6432.9
Subtracting 180 from 190 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.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 6432.95
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
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: 6432.95
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6432.95
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.

After the division, we end up with 6432.95 and a remainder of 0.0.
