532165 divided by 91 
The aim is to understand the frequency of 91 in 532165.

Going ahead to step 1:
When dividing 5 by 91, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 91

On to step 2:
91 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 91

Let's proceed to step 3:
If we divide 532 by 91, we get 5 and a remainder of 77.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 455 from 532 to get 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 91

Going ahead to step 4:
When dividing 771 by 91, we get 8 with a remainder of 43.
Record the quotient 8 as the next digit in the result. 
Result so far: 58.0
Subtract 728 from 771 to get 43.
Take the next digit (6) from the dividend and append it to 43, then repeat: 436 / 91

Going ahead to step 5:
If we divide 436 by 91, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 584.0
The remainder is 72 after subtracting 364 from 436.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 91

Going ahead to step 6:
725 divided by 91 is 7 with a remainder of 88.
Use 7 as the next digit of our solution. 
Result so far: 5847.0
The remainder is 88 after subtracting 637 from 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 7:
If we divide 880 by 91, we get 9 and a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 5847.9
Deduct 819 from 880 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
The number 91 fits into 610 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 5847.96
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 91 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 5847.967
Deduct 637 from 640 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 91 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5847.967
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
300 divided by 91 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 5847.96703
The remainder is 27 after subtracting 273 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
The number 91 fits into 270 2 times, leaving a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 5847.967032
Deduct 182 from 270 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Step 13:
880 divided by 91 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 5847.9670329
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 14:
610 divided by 91 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 5847.96703296
Deduct 546 from 610 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Our division results in 5847.96703296 with a remaining 6.4e-08.
