209686 ÷ 91 
We want to figure out the number of times 209686 can be divided by 91.

Step 1:
The number 91 fits into 2 0 times, leaving 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.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 91

Moving on to step 2:
When dividing 20 by 91, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 91

Step 3:
209 divided by 91 is 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 182 from 209 and we're left with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 91

Advancing to step 4:
91 goes into 276 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 23.0
Subtract 273 from 276 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 91

Let's proceed to step 5:
If we divide 38 by 91, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
Subtract 0 from 38 to get 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 91

Step 6:
If we divide 386 by 91, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 2304.0
Subtracting 364 from 386 leaves us with 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 7:
If we divide 220 by 91, we get 2 and a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2304.2
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
If we divide 380 by 91, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2304.24
Subtracting 364 from 380 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 2304.241
Subtracting 91 from 160 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 10:
690 divided by 91 is 7 with a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 2304.2417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
530 divided by 91 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 2304.24175
If we take 455 away from 530, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 12:
When dividing 750 by 91, we get 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 2304.241758
If we subtract 728 from 750, 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.

Advancing to step 13:
91 goes into 220 2 times with a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 2304.2417582
If we take 182 away from 220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
91 can be fit into 380 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 2304.24175824
Deduct 364 from 380 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 2304.24175824 with a remaining 1.6e-08.
