We look at the division of 87608875 by 336 
The aim is to understand the frequency of 336 in 87608875.

Step 1:
336 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 336

On to step 2:
When dividing 87 by 336, we get 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 336

Moving on to step 3:
336 can be fit into 876 2 times, resulting in a remainder of 204.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 672 from 876 and we're left with 204.
Include the next digit (0) from the dividend after 204, then repeat: 2040 / 336

Moving on to step 4:
When dividing 2040 by 336, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 2016 from 2040 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 336

Step 5:
248 divided by 336 is 0 with a remainder of 248.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
Subtract 0 from 248 to get 248.
Fetch the next digit (8) from the dividend, attach it to 248 and continue: 2488 / 336

Advancing to step 6:
336 can be fit into 2488 7 times, resulting in a remainder of 136.
The number 7 becomes the next digit in our result. 
Result so far: 2607.0
If we subtract 2352 from 2488, we get 136.
Include the next digit (7) from the dividend after 136, then repeat: 1367 / 336

Advancing to step 7:
The number 336 fits into 1367 4 times, leaving a remainder of 23.
Record the quotient 4 as the next digit in the result. 
Result so far: 26074.0
Deduct 1344 from 1367 and we're left with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 336

Step 8:
336 can be fit into 235 0 times, resulting in a remainder of 235.
Write down 0 as next digit of the result. 
Result so far: 260740.0
Subtracting 0 from 235 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
If we divide 2350 by 336, we get 6 and a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 260740.6
Deduct 2016 from 2350 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 10:
336 goes into 3340 9 times with a remainder of 316.
Put 9 as the next digit of the answer. 
Result so far: 260740.69
If we subtract 3024 from 3340, we get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 11:
336 goes into 3160 9 times with a remainder of 136.
Write down 9 as next digit of the result. 
Result so far: 260740.699
If we subtract 3024 from 3160, we get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 260740.699 with a remainder of 0.0136.
