554238 ÷ 75 
The aim is to understand the frequency of 75 in 554238.

Step 1:
When dividing 5 by 75, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 75

Going ahead to step 2:
The number 75 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 75

Step 3:
75 can be fit into 554 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 525 from 554, we get 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 75

Going ahead to step 4:
292 divided by 75 is 3 with a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtract 225 from 292 to get 67.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 75

Going ahead to step 5:
The number 75 fits into 673 8 times, leaving a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 738.0
If we take 600 away from 673, we end up with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 75

Step 6:
75 goes into 738 9 times with a remainder of 63.
Record the quotient 9 as the next digit in the result. 
Result so far: 7389.0
If we subtract 675 from 738, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
When dividing 630 by 75, we get 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 7389.8
The remainder is 30 after subtracting 600 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
75 can be fit into 300 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 7389.84
If we subtract 300 from 300, 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.

Going ahead to step 9:
75 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7389.84
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7389.84
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 result is 7389.84 with a remainder of 0.0.
