We look at the division of 91576169 by 366 
The aim is to understand the frequency of 366 in 91576169.

Moving on to step 1:
The number 366 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 366

Step 2:
366 goes into 91 0 times with a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Fetch the next digit (5) from the dividend, attach it to 91 and continue: 915 / 366

On to step 3:
The number 366 fits into 915 2 times, leaving a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 732 away from 915, we end up with 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 366

Let's proceed to step 4:
1837 divided by 366 is 5 with a remainder of 7.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 1830 from 1837 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 366

Going ahead to step 5:
76 divided by 366 is 0 with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 250.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (1) from the dividend and append it to 76, then repeat: 761 / 366

Advancing to step 6:
761 divided by 366 is 2 with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 2502.0
The remainder is 29 after subtracting 732 from 761.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 366

On to step 7:
366 can be fit into 296 0 times, resulting in a remainder of 296.
Put 0 as the next digit of the answer. 
Result so far: 25020.0
If we take 0 away from 296, we end up with 296.
Include the next digit (9) from the dividend after 296, then repeat: 2969 / 366

Going ahead to step 8:
366 goes into 2969 8 times with a remainder of 41.
The next digit of our result is 8. 
Result so far: 250208.0
Subtract 2928 from 2969 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
410 divided by 366 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 250208.1
Subtracting 366 from 410 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 10:
If we divide 440 by 366, we get 1 and a remainder of 74.
The number 1 becomes the next digit in our result. 
Result so far: 250208.11
If we take 366 away from 440, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The quotient of the division is 250208.11, and the remainder is 0.074.
