We look at the division of 209905 by 91 
Let's see how many times 91 fits into 209905.

Step 1:
If we divide 2 by 91, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 91

On to step 2:
When dividing 20 by 91, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 91

Going ahead to step 3:
209 divided by 91 is 2 with a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 182 from 209 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 91

Step 4:
91 can be fit into 279 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 273 from 279 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 91

Let's proceed to step 5:
When dividing 60 by 91, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 230.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (5) from the dividend, add it to 60, then carry on: 605 / 91

Going ahead to step 6:
The number 91 fits into 605 6 times, leaving a remainder of 59.
The next digit of our result is 6. 
Result so far: 2306.0
If we take 546 away from 605, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
The number 91 fits into 590 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2306.6
If we take 546 away from 590, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
91 goes into 440 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 2306.64
The remainder is 76 after subtracting 364 from 440.
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 9:
If we divide 760 by 91, we get 8 and a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 2306.648
If we subtract 728 from 760, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
91 goes into 320 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 2306.6483
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
If we divide 470 by 91, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 2306.64835
If we take 455 away from 470, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
91 goes into 150 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 2306.648351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 13:
590 divided by 91 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 2306.6483516
If we subtract 546 from 590, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
The number 91 fits into 440 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 2306.64835164
The remainder is 76 after subtracting 364 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 2306.64835164 with a remainder of 7.6e-08.
