We look at the division of 14991071 by 366 
The aim is to understand the frequency of 366 in 14991071.

Moving on to step 1:
366 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 366

Going ahead to step 2:
366 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 366

Step 3:
366 goes into 149 0 times with a remainder of 149.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 149, we end up with 149.
Append the next digit (9) from the dividend to 149 and continue with: 1499 / 366

Advancing to step 4:
If we divide 1499 by 366, we get 4 and a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 1464 from 1499 to get 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 366

Advancing to step 5:
366 can be fit into 351 0 times, resulting in a remainder of 351.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 351, we end up with 351.
Grab the next digit (0) from the dividend, add it to 351, then carry on: 3510 / 366

On to step 6:
366 can be fit into 3510 9 times, resulting in a remainder of 216.
Use 9 as the next digit of our solution. 
Result so far: 409.0
Subtracting 3294 from 3510 leaves us with 216.
Fetch the next digit (7) from the dividend, attach it to 216 and continue: 2167 / 366

Moving on to step 7:
366 goes into 2167 5 times with a remainder of 337.
Use 5 as the next digit of our solution. 
Result so far: 4095.0
The remainder is 337 after subtracting 1830 from 2167.
Fetch the next digit (1) from the dividend, attach it to 337 and continue: 3371 / 366

Step 8:
366 goes into 3371 9 times with a remainder of 77.
Use 9 as the next digit of our solution. 
Result so far: 40959.0
The remainder is 77 after subtracting 3294 from 3371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
770 divided by 366 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 40959.2
If we take 732 away from 770, we end up 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.

Moving on to step 10:
When dividing 380 by 366, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 40959.21
Subtracting 366 from 380 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 366 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 40959.21
Deduct 0 from 140 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 12:
366 goes into 1400 3 times with a remainder of 302.
The next digit of our result is 3. 
Result so far: 40959.2103
Subtract 1098 from 1400 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Moving on to step 13:
366 goes into 3020 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 40959.21038
Deduct 2928 from 3020 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 14:
366 goes into 920 2 times with a remainder of 188.
Write down 2 as next digit of the result. 
Result so far: 40959.210382
Subtract 732 from 920 to get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Let's proceed to step 15:
When dividing 1880 by 366, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 40959.2103825
If we subtract 1830 from 1880, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 16:
If we divide 500 by 366, we get 1 and a remainder of 134.
The next digit of our result is 1. 
Result so far: 40959.21038251
Subtract 366 from 500 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The quotient of the division is 40959.21038251, and the remainder is 1.34e-07.
