We're dividing 129933 by 81 
We want to divide 129933 by 81.

Let's proceed to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 81

Let's proceed to step 2:
When dividing 12 by 81, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 81

Moving on to step 3:
81 goes into 129 1 times with a remainder of 48.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 81 from 129 leaves us with 48.
Grab the next digit (9) from the dividend, add it to 48, then carry on: 489 / 81

Going ahead to step 4:
81 goes into 489 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 486 away from 489, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 81

Let's proceed to step 5:
When dividing 33 by 81, we get 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 160.0
Deduct 0 from 33 and we're left with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 81

Going ahead to step 6:
333 divided by 81 is 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 1604.0
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.

On to step 7:
81 goes into 90 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1604.1
If we subtract 81 from 90, we 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.

Let's proceed to step 8:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1604.11
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 1604.11 and a remainder of 0.009.
