We look at the division of 145489 by 81 
We're looking to find how many times 81 goes into 145489.

Let's proceed to step 1:
81 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 81

Let's proceed to step 2:
81 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 81

Going ahead to step 3:
81 goes into 145 1 times with a remainder of 64.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 64 after subtracting 81 from 145.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 81

Going ahead to step 4:
The number 81 fits into 644 7 times, leaving a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 567 from 644 and we're left with 77.
Grab the next digit (8) from the dividend, add it to 77, then carry on: 778 / 81

On to step 5:
If we divide 778 by 81, we get 9 and a remainder of 49.
The next digit of our result is 9. 
Result so far: 179.0
The remainder is 49 after subtracting 729 from 778.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 81

On to step 6:
499 divided by 81 is 6 with a remainder of 13.
The next digit of our result is 6. 
Result so far: 1796.0
If we subtract 486 from 499, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 81 is 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 1796.1
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 8:
When dividing 490 by 81, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1796.16
If we subtract 486 from 490, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
When dividing 40 by 81, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1796.16
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
If we divide 400 by 81, we get 4 and a remainder of 76.
The next digit of our result is 4. 
Result so far: 1796.1604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
If we divide 760 by 81, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 1796.16049
Subtract 729 from 760 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 12:
If we divide 310 by 81, we get 3 and a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 1796.160493
Subtracting 243 from 310 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 13:
If we divide 670 by 81, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 1796.1604938
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
The number 81 fits into 220 2 times, leaving a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 1796.16049382
Deduct 162 from 220 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 1796.16049382 and a remainder of 5.8e-08.
