Let's divide 209307 by 81
We want to figure out the number of times 209307 can be divided by 81.

On to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 81

Moving on to step 2:
If we divide 20 by 81, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Take the next digit (9) from the dividend and append it to 20, then repeat: 209 / 81

Going ahead to step 3:
81 goes into 209 2 times with a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 162 away from 209, we end up with 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 81

On to step 4:
473 divided by 81 is 5 with a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we take 405 away from 473, we end up with 68.
Take the next digit (0) from the dividend and append it to 68, then repeat: 680 / 81

Let's proceed to step 5:
81 goes into 680 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 258.0
Deduct 648 from 680 and we're left with 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 81

Moving on to step 6:
81 goes into 327 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 2584.0
Subtracting 324 from 327 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
The number 81 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 2584.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
The number 81 fits into 300 3 times, leaving a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 2584.03
Subtract 243 from 300 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 9:
81 can be fit into 570 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 2584.037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
If we divide 30 by 81, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 2584.037
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 81, we get 3 with a remainder of 57.
Record the quotient 3 as the next digit in the result. 
Result so far: 2584.03703
Deduct 243 from 300 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 12:
570 divided by 81 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2584.037037
The remainder is 3 after subtracting 567 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 81 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 2584.037037
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
81 goes into 300 3 times with a remainder of 57.
Use 3 as the next digit of our solution. 
Result so far: 2584.03703703
Subtracting 243 from 300 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 2584.03703703, with a leftover of 5.7e-08.
