52012399 divided by 75 
The aim is to understand the frequency of 75 in 52012399.

Let's proceed to step 1:
75 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 75

Step 2:
75 goes into 52 0 times with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (0) from the dividend, add it to 52, then carry on: 520 / 75

Step 3:
520 divided by 75 is 6 with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 450 from 520 to get 70.
Bring next digit (1) of the dividend behind the 70 and repeat the process: 701 / 75

Let's proceed to step 4:
75 can be fit into 701 9 times, resulting in a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we subtract 675 from 701, we get 26.
Take the next digit (2) from the dividend and append it to 26, then repeat: 262 / 75

Going ahead to step 5:
When dividing 262 by 75, we get 3 with a remainder of 37.
The next digit of our result is 3. 
Result so far: 693.0
If we subtract 225 from 262, we get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 75

Step 6:
If we divide 373 by 75, we get 4 and a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 6934.0
Deduct 300 from 373 and we're left with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 75

On to step 7:
739 divided by 75 is 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 69349.0
The remainder is 64 after subtracting 675 from 739.
Take the next digit (9) from the dividend and append it to 64, then repeat: 649 / 75

Advancing to step 8:
When dividing 649 by 75, we get 8 with a remainder of 49.
Record the quotient 8 as the next digit in the result. 
Result so far: 693498.0
If we take 600 away from 649, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
If we divide 490 by 75, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 693498.6
Subtracting 450 from 490 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
400 divided by 75 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 693498.65
Subtracting 375 from 400 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.

Let's proceed to step 11:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 693498.653
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
If we divide 250 by 75, we get 3 and a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 693498.6533
If we take 225 away from 250, 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.

The final result is 693498.6533 with a remainder of 0.00025.
