550506 divided by 75 
The aim is to understand the frequency of 75 in 550506.

Advancing to step 1:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 75

On to step 2:
75 goes into 55 0 times with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 75

Going ahead to step 3:
75 can be fit into 550 7 times, resulting in a remainder of 25.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 525 from 550 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 75

Advancing to step 4:
75 can be fit into 255 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 73.0
The remainder is 30 after subtracting 225 from 255.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 75

Going ahead to step 5:
75 goes into 300 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 734.0
If we subtract 300 from 300, we get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 75

Moving on to step 6:
75 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 7340.0
If we take 0 away from 6, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
The number 75 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 7340.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
75 can be fit into 600 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 7340.08
If we take 600 away from 600, 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.

Step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7340.08
Subtracting 0 from 0 leaves us 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.

Going ahead to step 10:
0 divided by 75 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7340.08
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 7340.08 and a remainder of 0.0.
