We look at the division of 75377757 by 325 
The aim is to understand the frequency of 325 in 75377757.

Step 1:
325 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 325

Going ahead to step 2:
325 can be fit into 75 0 times, resulting in a remainder of 75.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 325

Step 3:
If we divide 753 by 325, we get 2 and a remainder of 103.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 650 away from 753, we end up with 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 325

Let's proceed to step 4:
1037 divided by 325 is 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we subtract 975 from 1037, we get 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 325

Step 5:
When dividing 627 by 325, we get 1 with a remainder of 302.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we subtract 325 from 627, we get 302.
Bring next digit (7) of the dividend behind the 302 and repeat the process: 3027 / 325

Advancing to step 6:
If we divide 3027 by 325, we get 9 and a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 2319.0
Subtract 2925 from 3027 to get 102.
Grab the next digit (5) from the dividend, add it to 102, then carry on: 1025 / 325

Moving on to step 7:
325 goes into 1025 3 times with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 23193.0
If we subtract 975 from 1025, we get 50.
Take the next digit (7) from the dividend and append it to 50, then repeat: 507 / 325

Step 8:
The number 325 fits into 507 1 times, leaving a remainder of 182.
Use 1 as the next digit of our solution. 
Result so far: 231931.0
If we subtract 325 from 507, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Going ahead to step 9:
1820 divided by 325 is 5 with a remainder of 195.
Put 5 as the next digit of the answer. 
Result so far: 231931.5
Deduct 1625 from 1820 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 10:
1950 divided by 325 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 231931.56
Subtract 1950 from 1950 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
When dividing 0 by 325, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 231931.56
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
If we divide 0 by 325, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 231931.56
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 231931.56, with a leftover of 0.0.
