We look at the division of 143911 by 81 
Our goal is to divide 143911 by 81.

On to step 1:
81 goes into 1 0 times with 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.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 81

Going ahead to step 2:
The number 81 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 81

Step 3:
If we divide 143 by 81, we get 1 and a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 62 after subtracting 81 from 143.
Bring next digit (9) of the dividend behind the 62 and repeat the process: 629 / 81

Step 4:
629 divided by 81 is 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 62 after subtracting 567 from 629.
Grab the next digit (1) from the dividend, add it to 62, then carry on: 621 / 81

Let's proceed to step 5:
When dividing 621 by 81, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
If we take 567 away from 621, we end up with 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 81

Moving on to step 6:
81 goes into 541 6 times with a remainder of 55.
Write down 6 as next digit of the result. 
Result so far: 1776.0
The remainder is 55 after subtracting 486 from 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 7:
81 can be fit into 550 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 1776.6
If we subtract 486 from 550, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 8:
When dividing 640 by 81, we get 7 with a remainder of 73.
The next digit of our result is 7. 
Result so far: 1776.67
The remainder is 73 after subtracting 567 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
If we divide 730 by 81, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 1776.679
If we take 729 away from 730, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
81 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1776.679
Subtracting 0 from 10 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.

Advancing to step 11:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The next digit of our result is 1. 
Result so far: 1776.67901
If we subtract 81 from 100, we get 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 12:
The number 81 fits into 190 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 1776.679012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
If we divide 280 by 81, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 1776.6790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
The number 81 fits into 370 4 times, leaving a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 1776.67901234
If we subtract 324 from 370, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 1776.67901234, with a leftover of 4.6e-08.
