We're dividing 109309 by 81 
Our goal is to divide 109309 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

Let's proceed to step 2:
81 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 81

Let's proceed to step 3:
81 goes into 109 1 times with a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 81 from 109 to get 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 81

Going ahead to step 4:
If we divide 283 by 81, we get 3 and a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 243 from 283 leaves us with 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 81

On to step 5:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 134.0
If we take 324 away from 400, we end up with 76.
Take the next digit (9) from the dividend and append it to 76, then repeat: 769 / 81

Step 6:
81 can be fit into 769 9 times, resulting in a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 1349.0
The remainder is 40 after subtracting 729 from 769.
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 7:
If we divide 400 by 81, we get 4 and a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 1349.4
Subtracting 324 from 400 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
81 can be fit into 760 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 1349.49
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.

Going ahead to step 9:
81 goes into 310 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 1349.493
If we subtract 243 from 310, we 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.

Let's proceed to step 10:
When dividing 670 by 81, we get 8 with a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 1349.4938
Subtract 648 from 670 to 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.

On to step 11:
81 goes into 220 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 1349.49382
If we take 162 away from 220, we end up 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.

On to step 12:
580 divided by 81 is 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 1349.493827
Subtracting 567 from 580 leaves us 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.

Step 13:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 1349.4938271
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.

Advancing to step 14:
81 goes into 490 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 1349.49382716
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.

After the division, we end up with 1349.49382716 and a remainder of 4e-09.
