We're dividing 122492 by 81 
We want to divide 122492 by 81.

On to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 81

On to step 2:
12 divided by 81 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 81

Let's proceed to step 3:
The number 81 fits into 122 1 times, leaving a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 122, we end up with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 81

Moving on to step 4:
414 divided by 81 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 9 after subtracting 405 from 414.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 81

On to step 5:
99 divided by 81 is 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 151.0
Subtracting 81 from 99 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 81

Going ahead to step 6:
The number 81 fits into 182 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 1512.0
Subtracting 162 from 182 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 1512.2
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
When dividing 380 by 81, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 1512.24
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
560 divided by 81 is 6 with a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 1512.246
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
When dividing 740 by 81, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1512.2469
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 11:
When dividing 110 by 81, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1512.24691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 12:
81 goes into 290 3 times with a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 1512.246913
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 13:
The number 81 fits into 470 5 times, leaving a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 1512.2469135
The remainder is 65 after subtracting 405 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 14:
81 goes into 650 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1512.24691358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 1512.24691358, with a leftover of 2e-09.
