We're dividing 72126602 by 299 
The aim is to understand the frequency of 299 in 72126602.

Going ahead to step 1:
The number 299 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 299

Going ahead to step 2:
If we divide 72 by 299, we get 0 and a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (1) of the dividend behind the 72 and repeat the process: 721 / 299

Advancing to step 3:
The number 299 fits into 721 2 times, leaving a remainder of 123.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 598 from 721, we get 123.
Include the next digit (2) from the dividend after 123, then repeat: 1232 / 299

Let's proceed to step 4:
The number 299 fits into 1232 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 1196 from 1232 and we're left with 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 299

Moving on to step 5:
When dividing 366 by 299, we get 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 241.0
Subtract 299 from 366 to get 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 299

Moving on to step 6:
676 divided by 299 is 2 with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 2412.0
The remainder is 78 after subtracting 598 from 676.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 299

Going ahead to step 7:
The number 299 fits into 780 2 times, leaving a remainder of 182.
Use 2 as the next digit of our solution. 
Result so far: 24122.0
Deduct 598 from 780 and we're left with 182.
Include the next digit (2) from the dividend after 182, then repeat: 1822 / 299

Step 8:
299 can be fit into 1822 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 241226.0
Deduct 1794 from 1822 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
The number 299 fits into 280 0 times, leaving a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 241226.0
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 10:
299 can be fit into 2800 9 times, resulting in a remainder of 109.
Use 9 as the next digit of our solution. 
Result so far: 241226.09
Subtract 2691 from 2800 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

On to step 11:
If we divide 1090 by 299, we get 3 and a remainder of 193.
Put 3 as the next digit of the answer. 
Result so far: 241226.093
The remainder is 193 after subtracting 897 from 1090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

On to step 12:
If we divide 1930 by 299, we get 6 and a remainder of 136.
Put 6 as the next digit of the answer. 
Result so far: 241226.0936
Deduct 1794 from 1930 and we're left with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 13:
The number 299 fits into 1360 4 times, leaving a remainder of 164.
Write down 4 as next digit of the result. 
Result so far: 241226.09364
Subtracting 1196 from 1360 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.

Let's proceed to step 14:
299 goes into 1640 5 times with a remainder of 145.
The next digit of our result is 5. 
Result so far: 241226.093645
If we take 1495 away from 1640, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Going ahead to step 15:
The number 299 fits into 1450 4 times, leaving a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 241226.0936454
If we take 1196 away from 1450, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 16:
299 goes into 2540 8 times with a remainder of 148.
The number 8 becomes the next digit in our result. 
Result so far: 241226.09364548
Subtracting 2392 from 2540 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final outcome is 241226.09364548, with a leftover of 1.48e-07.
