We're dividing 900297 by 75 
The aim is to understand the frequency of 75 in 900297.

Going ahead to step 1:
The number 75 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 75

Step 2:
If we divide 90 by 75, we get 1 and a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 15 after subtracting 75 from 90.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 75

Step 3:
150 divided by 75 is 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 150 from 150 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 75

Moving on to step 4:
The number 75 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 2, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 75

Let's proceed to step 5:
29 divided by 75 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 1200.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (7) from the dividend, attach it to 29 and continue: 297 / 75

On to step 6:
75 can be fit into 297 3 times, resulting in a remainder of 72.
Record the quotient 3 as the next digit in the result. 
Result so far: 12003.0
If we take 225 away from 297, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
The number 75 fits into 720 9 times, leaving a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 12003.9
The remainder is 45 after subtracting 675 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 8:
75 can be fit into 450 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 12003.96
If we take 450 away from 450, 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.

On to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12003.96
Subtracting 0 from 0 leaves us 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.

On to step 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12003.96
If we subtract 0 from 0, we 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 12003.96, with a leftover of 0.0.
