652418 divided by 91 
The aim is to understand the frequency of 91 in 652418.

On to step 1:
91 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 91

Moving on to step 2:
When dividing 65 by 91, we get 0 with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (2) from the dividend and append it to 65, then repeat: 652 / 91

Going ahead to step 3:
When dividing 652 by 91, we get 7 with a remainder of 15.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 15 after subtracting 637 from 652.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 91

Moving on to step 4:
91 can be fit into 154 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
Subtracting 91 from 154 leaves us with 63.
Fetch the next digit (1) from the dividend, attach it to 63 and continue: 631 / 91

On to step 5:
91 can be fit into 631 6 times, resulting in a remainder of 85.
Record the quotient 6 as the next digit in the result. 
Result so far: 716.0
If we take 546 away from 631, we end up with 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 91

Let's proceed to step 6:
If we divide 858 by 91, we get 9 and a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 7169.0
If we take 819 away from 858, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
390 divided by 91 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 7169.4
The remainder is 26 after subtracting 364 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 91 is 2 with a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 7169.42
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
When dividing 780 by 91, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 7169.428
Deduct 728 from 780 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
91 can be fit into 520 5 times, resulting in a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7169.4285
Subtracting 455 from 520 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 11:
If we divide 650 by 91, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7169.42857
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
130 divided by 91 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 7169.428571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
When dividing 390 by 91, we get 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 7169.4285714
If we take 364 away from 390, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
The number 91 fits into 260 2 times, leaving a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 7169.42857142
The remainder is 78 after subtracting 182 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Our division results in 7169.42857142 with a remaining 7.8e-08.
