Let's divide 524608 by 91
The aim is to understand the frequency of 91 in 524608.

Let's proceed 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
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 91

Moving on to step 2:
52 divided by 91 is 0 with a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 91

On to step 3:
91 can be fit into 524 5 times, resulting in a remainder of 69.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 455 from 524 to get 69.
Append the next digit (6) from the dividend to 69 and continue with: 696 / 91

Advancing to step 4:
91 can be fit into 696 7 times, resulting in a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we subtract 637 from 696, we get 59.
Include the next digit (0) from the dividend after 59, then repeat: 590 / 91

Let's proceed to step 5:
The number 91 fits into 590 6 times, leaving a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 576.0
The remainder is 44 after subtracting 546 from 590.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 91

Moving on to step 6:
If we divide 448 by 91, we get 4 and a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 5764.0
Subtract 364 from 448 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 7:
91 can be fit into 840 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 5764.9
Subtracting 819 from 840 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
210 divided by 91 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 5764.92
The remainder is 28 after subtracting 182 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 91, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 5764.923
Subtracting 273 from 280 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
91 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 5764.923
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
The number 91 fits into 700 7 times, leaving a remainder of 63.
Use 7 as the next digit of our solution. 
Result so far: 5764.92307
The remainder is 63 after subtracting 637 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
If we divide 630 by 91, we get 6 and a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 5764.923076
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
When dividing 840 by 91, we get 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 5764.9230769
The remainder is 21 after subtracting 819 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
If we divide 210 by 91, we get 2 and a remainder of 28.
The next digit of our result is 2. 
Result so far: 5764.92307692
If we take 182 away from 210, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Our division results in 5764.92307692 with a remaining 2.8e-08.
