We're dividing 99490302 by 363 
The aim is to understand the frequency of 363 in 99490302.

Moving on to step 1:
9 divided by 363 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 363

Moving on to step 2:
When dividing 99 by 363, we get 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (4) from the dividend and append it to 99, then repeat: 994 / 363

On to step 3:
If we divide 994 by 363, we get 2 and a remainder of 268.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 726 from 994 leaves us with 268.
Fetch the next digit (9) from the dividend, attach it to 268 and continue: 2689 / 363

Going ahead to step 4:
363 can be fit into 2689 7 times, resulting in a remainder of 148.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 2541 from 2689 to get 148.
Fetch the next digit (0) from the dividend, attach it to 148 and continue: 1480 / 363

Going ahead to step 5:
1480 divided by 363 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 274.0
The remainder is 28 after subtracting 1452 from 1480.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 363

Going ahead to step 6:
When dividing 283 by 363, we get 0 with a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 2740.0
Deduct 0 from 283 and we're left with 283.
Fetch the next digit (0) from the dividend, attach it to 283 and continue: 2830 / 363

On to step 7:
363 can be fit into 2830 7 times, resulting in a remainder of 289.
Use 7 as the next digit of our solution. 
Result so far: 27407.0
Deduct 2541 from 2830 and we're left with 289.
Bring next digit (2) of the dividend behind the 289 and repeat the process: 2892 / 363

Going ahead to step 8:
If we divide 2892 by 363, we get 7 and a remainder of 351.
Record the quotient 7 as the next digit in the result. 
Result so far: 274077.0
If we take 2541 away from 2892, we end up with 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

On to step 9:
If we divide 3510 by 363, we get 9 and a remainder of 243.
Put 9 as the next digit of the answer. 
Result so far: 274077.9
Subtract 3267 from 3510 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Let's proceed to step 10:
2430 divided by 363 is 6 with a remainder of 252.
Use 6 as the next digit of our solution. 
Result so far: 274077.96
If we take 2178 away from 2430, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
When dividing 2520 by 363, we get 6 with a remainder of 342.
Record the quotient 6 as the next digit in the result. 
Result so far: 274077.966
Subtracting 2178 from 2520 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final result is 274077.966 with a remainder of 0.0342.
