109573 divided by 81 
Our goal is to divide 109573 by 81.

Moving on to step 1:
81 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 81

Advancing to step 2:
10 divided by 81 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 81

Let's proceed to step 3:
If we divide 109 by 81, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 81 away from 109, we end up with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 81

On to step 4:
If we divide 285 by 81, we get 3 and a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 243 from 285 and we're left with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 81

On to step 5:
427 divided by 81 is 5 with a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 135.0
Subtracting 405 from 427 leaves us with 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 81

Moving on to step 6:
When dividing 223 by 81, we get 2 with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 1352.0
Deduct 162 from 223 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 7:
81 goes into 610 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1352.7
Subtracting 567 from 610 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 8:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1352.75
If we take 405 away from 430, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
81 goes into 250 3 times with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1352.753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 10:
When dividing 70 by 81, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 1352.753
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
81 goes into 700 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 1352.75308
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 12:
If we divide 520 by 81, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 1352.753086
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
When dividing 340 by 81, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 1352.7530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
The number 81 fits into 160 1 times, leaving a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 1352.75308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

The final result is 1352.75308641 with a remainder of 7.9e-08.
