Let's divide 215512 by 91
We want to figure out the number of times 215512 can be divided by 91.

Step 1:
When dividing 2 by 91, we get 0 with 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.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 91

Let's proceed to step 2:
When dividing 21 by 91, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 91

On to step 3:
The number 91 fits into 215 2 times, leaving a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 182 from 215 leaves us with 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 91

Let's proceed to step 4:
91 can be fit into 335 3 times, resulting in a remainder of 62.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 273 away from 335, we end up with 62.
Bring next digit (1) of the dividend behind the 62 and repeat the process: 621 / 91

Moving on to step 5:
The number 91 fits into 621 6 times, leaving a remainder of 75.
The next digit of our result is 6. 
Result so far: 236.0
If we take 546 away from 621, we end up with 75.
Fetch the next digit (2) from the dividend, attach it to 75 and continue: 752 / 91

Moving on to step 6:
When dividing 752 by 91, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2368.0
The remainder is 24 after subtracting 728 from 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
The number 91 fits into 240 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 2368.2
The remainder is 58 after subtracting 182 from 240.
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 8:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 2368.26
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 91 fits into 340 3 times, leaving a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 2368.263
If we subtract 273 from 340, 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.

On to step 10:
91 can be fit into 670 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 2368.2637
Subtracting 637 from 670 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 11:
91 goes into 330 3 times with a remainder of 57.
Put 3 as the next digit of the answer. 
Result so far: 2368.26373
If we take 273 away from 330, we end up 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.

Let's proceed to step 12:
570 divided by 91 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2368.263736
The remainder is 24 after subtracting 546 from 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
If we divide 240 by 91, we get 2 and a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 2368.2637362
The remainder is 58 after subtracting 182 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
If we divide 580 by 91, we get 6 and a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 2368.26373626
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 2368.26373626 with a remaining 3.4e-08.
