We're dividing 623952 by 75 
The aim is to understand the frequency of 75 in 623952.

On to step 1:
When dividing 6 by 75, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 75

On to step 2:
75 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 75

Advancing to step 3:
If we divide 623 by 75, we get 8 and a remainder of 23.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 600 from 623 to get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 75

Step 4:
If we divide 239 by 75, we get 3 and a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 83.0
If we subtract 225 from 239, we get 14.
Grab the next digit (5) from the dividend, add it to 14, then carry on: 145 / 75

Going ahead to step 5:
If we divide 145 by 75, we get 1 and a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 831.0
Deduct 75 from 145 and we're left with 70.
Take the next digit (2) from the dividend and append it to 70, then repeat: 702 / 75

On to step 6:
If we divide 702 by 75, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 8319.0
The remainder is 27 after subtracting 675 from 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
The number 75 fits into 270 3 times, leaving a remainder of 45.
The number 3 becomes the next digit in our result. 
Result so far: 8319.3
Subtracting 225 from 270 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.

Step 8:
When dividing 450 by 75, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 8319.36
If we subtract 450 from 450, 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.

On to step 9:
75 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8319.36
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.

On to step 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8319.36
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.

Our division results in 8319.36 with a remaining 0.0.
