We look at the division of 80173495 by 336 
The aim is to understand the frequency of 336 in 80173495.

Let's proceed to step 1:
336 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 336

On to step 2:
80 divided by 336 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 336

Advancing to step 3:
If we divide 801 by 336, we get 2 and a remainder of 129.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 672 from 801 and we're left with 129.
Append the next digit (7) from the dividend to 129 and continue with: 1297 / 336

Let's proceed to step 4:
336 can be fit into 1297 3 times, resulting in a remainder of 289.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Deduct 1008 from 1297 and we're left with 289.
Take the next digit (3) from the dividend and append it to 289, then repeat: 2893 / 336

On to step 5:
336 can be fit into 2893 8 times, resulting in a remainder of 205.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
If we take 2688 away from 2893, we end up with 205.
Take the next digit (4) from the dividend and append it to 205, then repeat: 2054 / 336

Moving on to step 6:
336 can be fit into 2054 6 times, resulting in a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 2386.0
Subtract 2016 from 2054 to get 38.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 336

Step 7:
336 goes into 389 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 23861.0
The remainder is 53 after subtracting 336 from 389.
Bring next digit (5) of the dividend behind the 53 and repeat the process: 535 / 336

On to step 8:
336 can be fit into 535 1 times, resulting in a remainder of 199.
Write down 1 as next digit of the result. 
Result so far: 238611.0
If we take 336 away from 535, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Step 9:
336 goes into 1990 5 times with a remainder of 310.
Put 5 as the next digit of the answer. 
Result so far: 238611.5
If we take 1680 away from 1990, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Advancing to step 10:
The number 336 fits into 3100 9 times, leaving a remainder of 76.
The next digit of our result is 9. 
Result so far: 238611.59
Subtracting 3024 from 3100 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 11:
336 goes into 760 2 times with a remainder of 88.
The next digit of our result is 2. 
Result so far: 238611.592
Subtract 672 from 760 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
336 can be fit into 880 2 times, resulting in a remainder of 208.
Put 2 as the next digit of the answer. 
Result so far: 238611.5922
If we subtract 672 from 880, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 238611.5922 and a remainder of 0.00208.
