320528 divided by 75 
The aim is to understand the frequency of 75 in 320528.

Going ahead to step 1:
If we divide 3 by 75, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 75

Step 2:
The number 75 fits into 32 0 times, leaving a remainder of 32.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 75

Advancing to step 3:
75 can be fit into 320 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 300 from 320, we get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 75

On to step 4:
If we divide 205 by 75, we get 2 and a remainder of 55.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 55 after subtracting 150 from 205.
Grab the next digit (2) from the dividend, add it to 55, then carry on: 552 / 75

Step 5:
75 can be fit into 552 7 times, resulting in a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 427.0
If we take 525 away from 552, we end up with 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 75

Step 6:
The number 75 fits into 278 3 times, leaving a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 4273.0
If we take 225 away from 278, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
When dividing 530 by 75, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 4273.7
If we subtract 525 from 530, we 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.

Step 8:
If we divide 50 by 75, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4273.7
Subtracting 0 from 50 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.

Step 9:
When dividing 500 by 75, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 4273.706
Deduct 450 from 500 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 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 4273.7066
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.

The final result is 4273.7066 with a remainder of 0.0005.
