We look at the division of 213807 by 91 
We're looking to find how many times 91 goes into 213807.

Step 1:
When dividing 2 by 91, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 91

Going ahead to step 2:
21 divided by 91 is 0 with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 91

Moving on to step 3:
213 divided by 91 is 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 182 from 213 to get 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 91

On to step 4:
318 divided by 91 is 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 273 from 318, we get 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 91

Let's proceed to step 5:
91 can be fit into 450 4 times, resulting in a remainder of 86.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
If we take 364 away from 450, we end up with 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 91

On to step 6:
The number 91 fits into 867 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 2349.0
Subtracting 819 from 867 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
91 goes into 480 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2349.5
If we subtract 455 from 480, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
91 goes into 250 2 times with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 2349.52
Subtract 182 from 250 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
91 can be fit into 680 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 2349.527
Subtracting 637 from 680 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.

Step 10:
91 goes into 430 4 times with a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 2349.5274
Subtract 364 from 430 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
91 can be fit into 660 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2349.52747
Deduct 637 from 660 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
When dividing 230 by 91, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 2349.527472
If we take 182 away from 230, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 13:
91 can be fit into 480 5 times, resulting in a remainder of 25.
The next digit of our result is 5. 
Result so far: 2349.5274725
If we take 455 away from 480, 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.

Going ahead to step 14:
91 goes into 250 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 2349.52747252
Subtract 182 from 250 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The final result is 2349.52747252 with a remainder of 6.8e-08.
