We divide 103025 by 75
The aim is to understand the frequency of 75 in 103025.

On to step 1:
The number 75 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 75

Advancing to step 2:
If we divide 10 by 75, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 75

Advancing to step 3:
75 goes into 103 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 28 after subtracting 75 from 103.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 75

Let's proceed to step 4:
The number 75 fits into 280 3 times, leaving a remainder of 55.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 225 from 280 to get 55.
Take the next digit (2) from the dividend and append it to 55, then repeat: 552 / 75

Going ahead to step 5:
When dividing 552 by 75, we get 7 with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 137.0
If we take 525 away from 552, we end up with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 75

Going ahead to step 6:
The number 75 fits into 275 3 times, leaving a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 1373.0
If we subtract 225 from 275, we 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.

Moving on to step 7:
When dividing 500 by 75, we get 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 1373.6
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
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: 1373.66
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.

After the division, we end up with 1373.66 and a remainder of 0.05.
