We're dividing 86899504 by 325 
The aim is to understand the frequency of 325 in 86899504.

Advancing to step 1:
8 divided by 325 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 325

Going ahead to step 2:
86 divided by 325 is 0 with a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 325

Going ahead to step 3:
325 can be fit into 868 2 times, resulting in a remainder of 218.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 650 from 868, we get 218.
Bring next digit (9) of the dividend behind the 218 and repeat the process: 2189 / 325

On to step 4:
2189 divided by 325 is 6 with a remainder of 239.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 1950 from 2189 to get 239.
Include the next digit (9) from the dividend after 239, then repeat: 2399 / 325

Advancing to step 5:
If we divide 2399 by 325, we get 7 and a remainder of 124.
The next digit of our result is 7. 
Result so far: 267.0
If we take 2275 away from 2399, we end up with 124.
Append the next digit (5) from the dividend to 124 and continue with: 1245 / 325

Moving on to step 6:
If we divide 1245 by 325, we get 3 and a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 2673.0
Subtracting 975 from 1245 leaves us with 270.
Grab the next digit (0) from the dividend, add it to 270, then carry on: 2700 / 325

Advancing to step 7:
The number 325 fits into 2700 8 times, leaving a remainder of 100.
The number 8 becomes the next digit in our result. 
Result so far: 26738.0
If we subtract 2600 from 2700, we get 100.
Take the next digit (4) from the dividend and append it to 100, then repeat: 1004 / 325

Step 8:
1004 divided by 325 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 267383.0
Deduct 975 from 1004 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 9:
When dividing 290 by 325, we get 0 with a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 267383.0
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 10:
If we divide 2900 by 325, we get 8 and a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 267383.08
If we subtract 2600 from 2900, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
When dividing 3000 by 325, we get 9 with a remainder of 75.
The next digit of our result is 9. 
Result so far: 267383.089
If we take 2925 away from 3000, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 12:
325 can be fit into 750 2 times, resulting in a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 267383.0892
If we take 650 away from 750, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
The number 325 fits into 1000 3 times, leaving a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 267383.08923
If we take 975 away from 1000, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
When dividing 250 by 325, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 267383.08923
The remainder is 250 after subtracting 0 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 15:
The number 325 fits into 2500 7 times, leaving a remainder of 225.
Record the quotient 7 as the next digit in the result. 
Result so far: 267383.0892307
Subtracting 2275 from 2500 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 16:
If we divide 2250 by 325, we get 6 and a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 267383.08923076
If we subtract 1950 from 2250, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Our division results in 267383.08923076 with a remaining 3e-07.
