We're dividing 20397911 by 125 
Our goal is to divide 20397911 by 125.

Let's proceed to step 1:
When dividing 2 by 125, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 125

Moving on to step 2:
20 divided by 125 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 125

On to step 3:
203 divided by 125 is 1 with a remainder of 78.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 125 away from 203, we end up with 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 125

On to step 4:
125 goes into 789 6 times with a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we subtract 750 from 789, we get 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 125

Going ahead to step 5:
When dividing 397 by 125, we get 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 163.0
If we subtract 375 from 397, we get 22.
Bring next digit (9) of the dividend behind the 22 and repeat the process: 229 / 125

Moving on to step 6:
If we divide 229 by 125, we get 1 and a remainder of 104.
The next digit of our result is 1. 
Result so far: 1631.0
If we subtract 125 from 229, we get 104.
Append the next digit (1) from the dividend to 104 and continue with: 1041 / 125

On to step 7:
The number 125 fits into 1041 8 times, leaving a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 16318.0
The remainder is 41 after subtracting 1000 from 1041.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 125

On to step 8:
125 can be fit into 411 3 times, resulting in a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 163183.0
Subtracting 375 from 411 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
When dividing 360 by 125, we get 2 with a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 163183.2
Subtracting 250 from 360 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
If we divide 1100 by 125, we get 8 and a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 163183.28
If we subtract 1000 from 1100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
When dividing 1000 by 125, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 163183.288
Deduct 1000 from 1000 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.

In conclusion, the division gives 163183.288 with a balance of 0.0.
