We're dividing 2596 by 325 
The aim is to understand the frequency of 325 in 2596.

Moving on to step 1:
325 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 325

Advancing to step 2:
325 can be fit into 25 0 times, resulting in a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 325

On to step 3:
If we divide 259 by 325, we get 0 and a remainder of 259.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 259, we end up with 259.
Bring next digit (6) of the dividend behind the 259 and repeat the process: 2596 / 325

Advancing to step 4:
325 can be fit into 2596 7 times, resulting in a remainder of 321.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 2275 away from 2596, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 5:
325 can be fit into 3210 9 times, resulting in a remainder of 285.
Write down 9 as next digit of the result. 
Result so far: 7.9
Deduct 2925 from 3210 and we're left with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Going ahead to step 6:
If we divide 2850 by 325, we get 8 and a remainder of 250.
Record the quotient 8 as the next digit in the result. 
Result so far: 7.98
If we subtract 2600 from 2850, 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 7:
When dividing 2500 by 325, we get 7 with a remainder of 225.
The next digit of our result is 7. 
Result so far: 7.987
Deduct 2275 from 2500 and we're left 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.

Step 8:
When dividing 2250 by 325, we get 6 with a remainder of 300.
Record the quotient 6 as the next digit in the result. 
Result so far: 7.9876
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.

Let's proceed to step 9:
325 goes into 3000 9 times with a remainder of 75.
Put 9 as the next digit of the answer. 
Result so far: 7.98769
Deduct 2925 from 3000 and we're left 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.

Advancing to step 10:
The number 325 fits into 750 2 times, leaving a remainder of 100.
Use 2 as the next digit of our solution. 
Result so far: 7.987692
If we subtract 650 from 750, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
325 goes into 1000 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 7.9876923
Subtracting 975 from 1000 leaves us 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 12:
The number 325 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 7.9876923
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 7.9876923, with a leftover of 2.5e-07.
