Let's divide 660506 by 75
The aim is to understand the frequency of 75 in 660506.

On to step 1:
75 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 75

Step 2:
The number 75 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (0) from the dividend, add it to 66, then carry on: 660 / 75

Advancing to step 3:
If we divide 660 by 75, we get 8 and a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 600 from 660, we get 60.
Append the next digit (5) from the dividend to 60 and continue with: 605 / 75

Let's proceed to step 4:
When dividing 605 by 75, we get 8 with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 5 after subtracting 600 from 605.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 75

Moving on to step 5:
The number 75 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 880.0
Deduct 0 from 50 and we're left with 50.
Grab the next digit (6) from the dividend, add it to 50, then carry on: 506 / 75

Going ahead to step 6:
506 divided by 75 is 6 with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 8806.0
The remainder is 56 after subtracting 450 from 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 7:
560 divided by 75 is 7 with a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 8806.7
Deduct 525 from 560 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 8:
When dividing 350 by 75, we get 4 with a remainder of 50.
Put 4 as the next digit of the answer. 
Result so far: 8806.74
If we subtract 300 from 350, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
The next digit of our result is 6. 
Result so far: 8806.746
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 8806.7466
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8806.7466, with a leftover of 0.0005.
