We're dividing 131439 by 20 
We want to divide 131439 by 20.

Advancing to step 1:
1 divided by 20 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 20

Step 2:
The number 20 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 20

Step 3:
20 can be fit into 131 6 times, resulting in a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 11 after subtracting 120 from 131.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 20

Advancing to step 4:
If we divide 114 by 20, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtracting 100 from 114 leaves us with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 20

Step 5:
When dividing 143 by 20, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 657.0
Subtracting 140 from 143 leaves us with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Moving on to step 6:
20 goes into 39 1 times with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 6571.0
Subtracting 20 from 39 leaves us 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.

Moving on to step 7:
20 can be fit into 190 9 times, resulting in a remainder of 10.
The next digit of our result is 9. 
Result so far: 6571.9
The remainder is 10 after subtracting 180 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 6571.95
If we subtract 100 from 100, 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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6571.95
Subtract 0 from 0 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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6571.95
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.

In conclusion, the division gives 6571.95 with a balance of 0.0.
