We look at the division of 30174082 by 301 
The aim is to understand the frequency of 301 in 30174082.

On to step 1:
301 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 301

Step 2:
If we divide 30 by 301, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 301

Going ahead to step 3:
The number 301 fits into 301 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 301 from 301 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 301

On to step 4:
7 divided by 301 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 301

Step 5:
301 goes into 74 0 times with a remainder of 74.
The next digit of our result is 0. 
Result so far: 100.0
Deduct 0 from 74 and we're left with 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 301

Moving on to step 6:
If we divide 740 by 301, we get 2 and a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 1002.0
If we take 602 away from 740, we end up with 138.
Include the next digit (8) from the dividend after 138, then repeat: 1388 / 301

On to step 7:
301 can be fit into 1388 4 times, resulting in a remainder of 184.
Use 4 as the next digit of our solution. 
Result so far: 10024.0
Deduct 1204 from 1388 and we're left with 184.
Grab the next digit (2) from the dividend, add it to 184, then carry on: 1842 / 301

Step 8:
1842 divided by 301 is 6 with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 100246.0
If we take 1806 away from 1842, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 9:
If we divide 360 by 301, we get 1 and a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 100246.1
If we take 301 away from 360, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
If we divide 590 by 301, we get 1 and a remainder of 289.
Put 1 as the next digit of the answer. 
Result so far: 100246.11
The remainder is 289 after subtracting 301 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

The final outcome is 100246.11, with a leftover of 0.289.
