96651 divided by 91 
The aim is to understand the frequency of 91 in 96651.

Let's proceed to step 1:
9 divided by 91 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 91

Let's proceed to step 2:
When dividing 96 by 91, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 91 from 96 leaves us with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 91

On to step 3:
56 divided by 91 is 0 with a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 56, we end up with 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 91

Advancing to step 4:
The number 91 fits into 565 6 times, leaving a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 106.0
Deduct 546 from 565 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 91

Step 5:
91 can be fit into 191 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 1062.0
If we subtract 182 from 191, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 6:
91 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 1062.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 7:
The number 91 fits into 900 9 times, leaving a remainder of 81.
The number 9 becomes the next digit in our result. 
Result so far: 1062.09
The remainder is 81 after subtracting 819 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 8:
810 divided by 91 is 8 with a remainder of 82.
The next digit of our result is 8. 
Result so far: 1062.098
If we take 728 away from 810, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
If we divide 820 by 91, we get 9 and a remainder of 1.
The next digit of our result is 9. 
Result so far: 1062.0989
If we subtract 819 from 820, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
The number 91 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 1062.0989
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 91 fits into 100 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1062.098901
Subtract 91 from 100 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
The number 91 fits into 90 0 times, leaving a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 1062.098901
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 13:
If we divide 900 by 91, we get 9 and a remainder of 81.
The next digit of our result is 9. 
Result so far: 1062.09890109
If we take 819 away from 900, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 1062.09890109 with a remaining 8.1e-08.
