We're dividing 180392 by 81 
We're looking to find how many times 81 goes into 180392.

Let's proceed to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 81

Going ahead to step 2:
When dividing 18 by 81, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 18, we get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 81

On to step 3:
The number 81 fits into 180 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 162 from 180, we get 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 81

Advancing to step 4:
81 goes into 183 2 times with a remainder of 21.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 162 from 183, we get 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 81

Going ahead to step 5:
If we divide 219 by 81, we get 2 and a remainder of 57.
Record the quotient 2 as the next digit in the result. 
Result so far: 222.0
Subtract 162 from 219 to get 57.
Include the next digit (2) from the dividend after 57, then repeat: 572 / 81

Advancing to step 6:
When dividing 572 by 81, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 2227.0
Subtracting 567 from 572 leaves us 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.

Let's proceed to step 7:
When dividing 50 by 81, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 2227.0
If we subtract 0 from 50, we get 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 8:
The number 81 fits into 500 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 2227.06
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 9:
When dividing 140 by 81, we get 1 with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 2227.061
Subtracting 81 from 140 leaves us 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.

Let's proceed to step 10:
If we divide 590 by 81, we get 7 and a remainder of 23.
The next digit of our result is 7. 
Result so far: 2227.0617
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 11:
The number 81 fits into 230 2 times, leaving a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 2227.06172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 12:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 2227.061728
If we take 648 away from 680, we end up 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.

Step 13:
320 divided by 81 is 3 with a remainder of 77.
Write down 3 as next digit of the result. 
Result so far: 2227.0617283
Subtracting 243 from 320 leaves us 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.

On to step 14:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 2227.06172839
Subtract 729 from 770 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 2227.06172839 with a remainder of 4.1e-08.
