Let's divide 216758 by 91
The aim is to understand the frequency of 91 in 216758.

Moving on to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 91

Going ahead to step 2:
21 divided by 91 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 91

Let's proceed to step 3:
When dividing 216 by 91, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 182 from 216 leaves us with 34.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 91

On to step 4:
When dividing 347 by 91, we get 3 with a remainder of 74.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 273 from 347 to get 74.
Bring next digit (5) of the dividend behind the 74 and repeat the process: 745 / 91

On to step 5:
If we divide 745 by 91, we get 8 and a remainder of 17.
The next digit of our result is 8. 
Result so far: 238.0
The remainder is 17 after subtracting 728 from 745.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 91

On to step 6:
91 can be fit into 178 1 times, resulting in a remainder of 87.
The number 1 becomes the next digit in our result. 
Result so far: 2381.0
If we subtract 91 from 178, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 7:
870 divided by 91 is 9 with a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 2381.9
Subtract 819 from 870 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 2381.95
The remainder is 55 after subtracting 455 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
550 divided by 91 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2381.956
The remainder is 4 after subtracting 546 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
The number 91 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2381.956
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
91 can be fit into 400 4 times, resulting in a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2381.95604
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 12:
When dividing 360 by 91, we get 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 2381.956043
Deduct 273 from 360 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
91 goes into 870 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 2381.9560439
Subtracting 819 from 870 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 14:
The number 91 fits into 510 5 times, leaving a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 2381.95604395
Deduct 455 from 510 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 2381.95604395 with a remaining 5.5e-08.
