We look at the division of 128597 by 81 
We're looking to find how many times 81 goes into 128597.

On to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 81

Let's proceed to step 2:
81 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 81

Let's proceed to step 3:
128 divided by 81 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 128 leaves us with 47.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 81

Moving on to step 4:
81 goes into 475 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 405 from 475 to get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 81

Moving on to step 5:
81 goes into 709 8 times with a remainder of 61.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 648 from 709 to get 61.
Append the next digit (7) from the dividend to 61 and continue with: 617 / 81

Step 6:
The number 81 fits into 617 7 times, leaving a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
If we take 567 away from 617, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
81 can be fit into 500 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1587.6
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
140 divided by 81 is 1 with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 1587.61
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
81 goes into 590 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 1587.617
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 10:
230 divided by 81 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 1587.6172
The remainder is 68 after subtracting 162 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 1587.61728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 81 fits into 320 3 times, leaving a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 1587.617283
Deduct 243 from 320 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 13:
81 goes into 770 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 1587.6172839
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1587.61728395
If we take 405 away from 410, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 1587.61728395 with a balance of 5e-09.
