We're looking to find how many times 128 goes into 20588172.

Going ahead to step 1:
128 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 128

Going ahead to step 2:
128 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 128

Moving on to step 3:
The number 128 fits into 205 1 times, leaving a remainder of 77.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 128 from 205 to get 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 128

Let's proceed to step 4:
If we divide 778 by 128, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 10 after subtracting 768 from 778.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 128

Moving on to step 5:
128 goes into 108 0 times with a remainder of 108.
The next digit of our result is 0. 
Result so far: 160.0
The remainder is 108 after subtracting 0 from 108.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 128

Advancing to step 6:
128 can be fit into 1081 8 times, resulting in a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 1608.0
The remainder is 57 after subtracting 1024 from 1081.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 128

Going ahead to step 7:
The number 128 fits into 577 4 times, leaving a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 16084.0
If we subtract 512 from 577, we get 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 128

Advancing to step 8:
The number 128 fits into 652 5 times, leaving a remainder of 12.
The next digit of our result is 5. 
Result so far: 160845.0
If we take 640 away from 652, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
128 can be fit into 120 0 times, resulting in a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 160845.0
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
128 can be fit into 1200 9 times, resulting in a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 160845.09
Subtract 1152 from 1200 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 11:
480 divided by 128 is 3 with a remainder of 96.
Record the quotient 3 as the next digit in the result. 
Result so far: 160845.093
Subtracting 384 from 480 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
The number 128 fits into 960 7 times, leaving a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 160845.0937
If we take 896 away from 960, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
When dividing 640 by 128, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 160845.09375
If we subtract 640 from 640, 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.

Step 14:
The number 128 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 160845.09375
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.

Step 15:
128 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 160845.09375
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.

In conclusion, the division gives 160845.09375 with a balance of 0.0.
