We're dividing 556783 by 75 
The aim is to understand the frequency of 75 in 556783.

Let's proceed to step 1:
75 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 75

Advancing to step 2:
If we divide 55 by 75, we get 0 and a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 75

Step 3:
The number 75 fits into 556 7 times, leaving a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 31 after subtracting 525 from 556.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 75

On to step 4:
When dividing 317 by 75, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 300 from 317 and we're left with 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 75

On to step 5:
75 can be fit into 178 2 times, resulting in a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 742.0
If we subtract 150 from 178, we get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 75

Let's proceed to step 6:
75 goes into 283 3 times with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 7423.0
If we take 225 away from 283, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 7:
If we divide 580 by 75, we get 7 and a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 7423.7
The remainder is 55 after subtracting 525 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 8:
When dividing 550 by 75, we get 7 with a remainder of 25.
The number 7 becomes the next digit in our result. 
Result so far: 7423.77
Subtract 525 from 550 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 7423.77, and the remainder is 0.025.
