756788 divided by 75 
The aim is to understand the frequency of 75 in 756788.

Step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 75

Advancing to step 2:
The number 75 fits into 75 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 75 away from 75, we end up with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 75

Advancing to step 3:
75 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 75

Let's proceed to step 4:
67 divided by 75 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 100.0
If we take 0 away from 67, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 75

Let's proceed to step 5:
75 can be fit into 678 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1009.0
Deduct 675 from 678 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 75

Advancing to step 6:
If we divide 38 by 75, we get 0 and a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 10090.0
If we subtract 0 from 38, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
The number 75 fits into 380 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10090.5
Subtract 375 from 380 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
75 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10090.5
Deduct 0 from 50 and we're left 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.

Advancing to step 9:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 10090.506
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.

On to step 10:
If we divide 500 by 75, we get 6 and a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 10090.5066
Subtracting 450 from 500 leaves us 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.

The quotient of the division is 10090.5066, and the remainder is 0.0005.
