We're dividing 159952 by 81 
We want to figure out the number of times 159952 can be divided by 81.

Let's proceed to step 1:
1 divided by 81 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 81

On to step 2:
If we divide 15 by 81, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 81

Going ahead to step 3:
If we divide 159 by 81, we get 1 and a remainder of 78.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 81 away from 159, we end up with 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 81

Step 4:
789 divided by 81 is 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we subtract 729 from 789, we get 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 81

On to step 5:
The number 81 fits into 605 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
Subtract 567 from 605 to get 38.
Fetch the next digit (2) from the dividend, attach it to 38 and continue: 382 / 81

Moving on to step 6:
81 can be fit into 382 4 times, resulting in a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
If we subtract 324 from 382, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
If we divide 580 by 81, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 1974.7
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
If we divide 130 by 81, we get 1 and a remainder of 49.
The next digit of our result is 1. 
Result so far: 1974.71
Deduct 81 from 130 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 9:
If we divide 490 by 81, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1974.716
Subtract 486 from 490 to 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.

Going ahead to step 10:
The number 81 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 1974.716
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
When dividing 400 by 81, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 1974.71604
Subtract 324 from 400 to 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 12:
81 can be fit into 760 9 times, resulting in a remainder of 31.
The next digit of our result is 9. 
Result so far: 1974.716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
81 can be fit into 310 3 times, resulting in a remainder of 67.
The next digit of our result is 3. 
Result so far: 1974.7160493
Subtract 243 from 310 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 14:
81 goes into 670 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1974.71604938
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.

The final result is 1974.71604938 with a remainder of 2.2e-08.
