We divide 77598728 by 325
The aim is to understand the frequency of 325 in 77598728.

Step 1:
7 divided by 325 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 325

Moving on to step 2:
77 divided by 325 is 0 with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 325

Moving on to step 3:
325 goes into 775 2 times with a remainder of 125.
The next digit of our result is 2. 
Result so far: 2.0
If we take 650 away from 775, we end up with 125.
Grab the next digit (9) from the dividend, add it to 125, then carry on: 1259 / 325

Step 4:
325 can be fit into 1259 3 times, resulting in a remainder of 284.
The next digit of our result is 3. 
Result so far: 23.0
Deduct 975 from 1259 and we're left with 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 325

Advancing to step 5:
2848 divided by 325 is 8 with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 238.0
Deduct 2600 from 2848 and we're left with 248.
Grab the next digit (7) from the dividend, add it to 248, then carry on: 2487 / 325

Going ahead to step 6:
If we divide 2487 by 325, we get 7 and a remainder of 212.
Use 7 as the next digit of our solution. 
Result so far: 2387.0
Subtract 2275 from 2487 to get 212.
Bring next digit (2) of the dividend behind the 212 and repeat the process: 2122 / 325

Advancing to step 7:
325 goes into 2122 6 times with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 23876.0
Deduct 1950 from 2122 and we're left with 172.
Bring next digit (8) of the dividend behind the 172 and repeat the process: 1728 / 325

Let's proceed to step 8:
If we divide 1728 by 325, we get 5 and a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 238765.0
The remainder is 103 after subtracting 1625 from 1728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 9:
If we divide 1030 by 325, we get 3 and a remainder of 55.
Use 3 as the next digit of our solution. 
Result so far: 238765.3
If we take 975 away from 1030, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 10:
325 goes into 550 1 times with a remainder of 225.
Write down 1 as next digit of the result. 
Result so far: 238765.31
If we subtract 325 from 550, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Moving on to step 11:
The number 325 fits into 2250 6 times, leaving a remainder of 300.
Put 6 as the next digit of the answer. 
Result so far: 238765.316
The remainder is 300 after subtracting 1950 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 12:
325 can be fit into 3000 9 times, resulting in a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 238765.3169
Subtracting 2925 from 3000 leaves us 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.

Moving on to step 13:
When dividing 750 by 325, we get 2 with a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 238765.31692
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.

Let's proceed to step 14:
325 can be fit into 1000 3 times, resulting in a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 238765.316923
Deduct 975 from 1000 and we're left 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.

Going ahead to step 15:
If we divide 250 by 325, we get 0 and a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 238765.316923
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

On to step 16:
When dividing 2500 by 325, we get 7 with a remainder of 225.
Record the quotient 7 as the next digit in the result. 
Result so far: 238765.31692307
Subtract 2275 from 2500 to get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final result is 238765.31692307 with a remainder of 2.25e-07.
