99591254 divided by 299 
The aim is to understand the frequency of 299 in 99591254.

Moving on to step 1:
If we divide 9 by 299, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 299

Going ahead to step 2:
When dividing 99 by 299, we get 0 with a remainder of 99.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Grab the next digit (5) from the dividend, add it to 99, then carry on: 995 / 299

Step 3:
995 divided by 299 is 3 with a remainder of 98.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 98 after subtracting 897 from 995.
Grab the next digit (9) from the dividend, add it to 98, then carry on: 989 / 299

Step 4:
299 goes into 989 3 times with a remainder of 92.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 897 from 989 leaves us with 92.
Include the next digit (1) from the dividend after 92, then repeat: 921 / 299

Advancing to step 5:
299 can be fit into 921 3 times, resulting in a remainder of 24.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
If we subtract 897 from 921, we get 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 299

Advancing to step 6:
299 can be fit into 242 0 times, resulting in a remainder of 242.
Record the quotient 0 as the next digit in the result. 
Result so far: 3330.0
Deduct 0 from 242 and we're left with 242.
Fetch the next digit (5) from the dividend, attach it to 242 and continue: 2425 / 299

Step 7:
The number 299 fits into 2425 8 times, leaving a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 33308.0
The remainder is 33 after subtracting 2392 from 2425.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 299

Going ahead to step 8:
334 divided by 299 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 333081.0
If we subtract 299 from 334, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 299 fits into 350 1 times, leaving a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 333081.1
If we subtract 299 from 350, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 10:
299 can be fit into 510 1 times, resulting in a remainder of 211.
Record the quotient 1 as the next digit in the result. 
Result so far: 333081.11
The remainder is 211 after subtracting 299 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

The final outcome is 333081.11, with a leftover of 0.211.
