We look at the division of 501447 by 75 
The aim is to understand the frequency of 75 in 501447.

Advancing to step 1:
75 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 75

Moving on to step 2:
The number 75 fits into 50 0 times, leaving a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (1) from the dividend and append it to 50, then repeat: 501 / 75

Step 3:
When dividing 501 by 75, we get 6 with a remainder of 51.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 450 from 501, we get 51.
Grab the next digit (4) from the dividend, add it to 51, then carry on: 514 / 75

On to step 4:
The number 75 fits into 514 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 66.0
If we take 450 away from 514, we end up with 64.
Bring next digit (4) of the dividend behind the 64 and repeat the process: 644 / 75

Moving on to step 5:
75 goes into 644 8 times with a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 668.0
If we subtract 600 from 644, we get 44.
Bring next digit (7) of the dividend behind the 44 and repeat the process: 447 / 75

Let's proceed to step 6:
75 goes into 447 5 times with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 6685.0
Deduct 375 from 447 and we're left 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.

On to step 7:
When dividing 720 by 75, we get 9 with a remainder of 45.
The next digit of our result is 9. 
Result so far: 6685.9
Subtracting 675 from 720 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
The number 75 fits into 450 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6685.96
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.

Advancing to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6685.96
Subtract 0 from 0 to 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 10:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6685.96
If we take 0 away from 0, 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.

The final outcome is 6685.96, with a leftover of 0.0.
