527361 divided by 91 
The aim is to understand the frequency of 91 in 527361.

Going ahead to step 1:
5 divided by 91 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 91

Advancing to step 2:
When dividing 52 by 91, we get 0 with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Grab the next digit (7) from the dividend, add it to 52, then carry on: 527 / 91

Going ahead to step 3:
If we divide 527 by 91, we get 5 and a remainder of 72.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 455 from 527 and we're left with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 91

Moving on to step 4:
723 divided by 91 is 7 with a remainder of 86.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtracting 637 from 723 leaves us with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 91

Let's proceed to step 5:
866 divided by 91 is 9 with a remainder of 47.
The next digit of our result is 9. 
Result so far: 579.0
The remainder is 47 after subtracting 819 from 866.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 91

Let's proceed to step 6:
91 can be fit into 471 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 5795.0
Subtracting 455 from 471 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 5795.1
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
When dividing 690 by 91, we get 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 5795.17
Deduct 637 from 690 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 9:
91 goes into 530 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5795.175
Deduct 455 from 530 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
91 goes into 750 8 times with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 5795.1758
Subtracting 728 from 750 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 11:
The number 91 fits into 220 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 5795.17582
Subtracting 182 from 220 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 12:
When dividing 380 by 91, we get 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 5795.175824
Subtract 364 from 380 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
91 goes into 160 1 times with a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 5795.1758241
Deduct 91 from 160 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 14:
91 goes into 690 7 times with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 5795.17582417
The remainder is 53 after subtracting 637 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Our division results in 5795.17582417 with a remaining 5.3e-08.
