90995303 divided by 366 
The aim is to understand the frequency of 366 in 90995303.

Advancing to step 1:
366 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 366

Moving on to step 2:
If we divide 90 by 366, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 366

Advancing to step 3:
When dividing 909 by 366, we get 2 with a remainder of 177.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 732 from 909 leaves us with 177.
Fetch the next digit (9) from the dividend, attach it to 177 and continue: 1779 / 366

On to step 4:
If we divide 1779 by 366, we get 4 and a remainder of 315.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we take 1464 away from 1779, we end up with 315.
Take the next digit (5) from the dividend and append it to 315, then repeat: 3155 / 366

Step 5:
366 can be fit into 3155 8 times, resulting in a remainder of 227.
The next digit of our result is 8. 
Result so far: 248.0
The remainder is 227 after subtracting 2928 from 3155.
Bring next digit (3) of the dividend behind the 227 and repeat the process: 2273 / 366

Let's proceed to step 6:
366 can be fit into 2273 6 times, resulting in a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 2486.0
If we subtract 2196 from 2273, we get 77.
Take the next digit (0) from the dividend and append it to 77, then repeat: 770 / 366

Going ahead to step 7:
The number 366 fits into 770 2 times, leaving a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 24862.0
The remainder is 38 after subtracting 732 from 770.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 366

Let's proceed to step 8:
When dividing 383 by 366, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 248621.0
Deduct 366 from 383 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
170 divided by 366 is 0 with a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 248621.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
The number 366 fits into 1700 4 times, leaving a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 248621.04
If we subtract 1464 from 1700, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 11:
366 goes into 2360 6 times with a remainder of 164.
The next digit of our result is 6. 
Result so far: 248621.046
Subtracting 2196 from 2360 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 12:
366 can be fit into 1640 4 times, resulting in a remainder of 176.
The number 4 becomes the next digit in our result. 
Result so far: 248621.0464
Subtracting 1464 from 1640 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
When dividing 1760 by 366, we get 4 with a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 248621.04644
Deduct 1464 from 1760 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 248621.04644, with a leftover of 0.000296.
