373099 divided by 75 
The aim is to understand the frequency of 75 in 373099.

Moving on to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 75

Let's proceed to step 2:
37 divided by 75 is 0 with a remainder of 37.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 75

Step 3:
75 can be fit into 373 4 times, resulting in a remainder of 73.
The next digit of our result is 4. 
Result so far: 4.0
If we take 300 away from 373, we end up with 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 75

On to step 4:
75 goes into 730 9 times with a remainder of 55.
The next digit of our result is 9. 
Result so far: 49.0
If we take 675 away from 730, we end up with 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 75

Moving on to step 5:
The number 75 fits into 559 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 497.0
Subtracting 525 from 559 leaves us with 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 75

Moving on to step 6:
The number 75 fits into 349 4 times, leaving a remainder of 49.
The next digit of our result is 4. 
Result so far: 4974.0
Deduct 300 from 349 and we're left 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.

Moving on to step 7:
75 can be fit into 490 6 times, resulting in a remainder of 40.
Use 6 as the next digit of our solution. 
Result so far: 4974.6
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.

Step 8:
If we divide 400 by 75, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 4974.65
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.

Moving on to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 4974.653
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.

Advancing to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 4974.6533
Subtracting 225 from 250 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.

The final outcome is 4974.6533, with a leftover of 0.00025.
