We're dividing 125073 by 81 
We want to divide 125073 by 81.

Going ahead to step 1:
If we divide 1 by 81, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 81

On to step 2:
81 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 81

Going ahead to step 3:
If we divide 125 by 81, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 81 from 125 and we're left with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 81

Step 4:
The number 81 fits into 440 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 405 away from 440, we end up with 35.
Grab the next digit (7) from the dividend, add it to 35, then carry on: 357 / 81

Let's proceed to step 5:
357 divided by 81 is 4 with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 154.0
The remainder is 33 after subtracting 324 from 357.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 81

Let's proceed to step 6:
If we divide 333 by 81, we get 4 and a remainder of 9.
The next digit of our result is 4. 
Result so far: 1544.0
Subtract 324 from 333 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
81 goes into 90 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1544.1
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
If we divide 90 by 81, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1544.11
Subtract 81 from 90 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 1544.11 with a remainder of 0.009.
