115203 ÷ 75 
The aim is to understand the frequency of 75 in 115203.

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.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 75

Going ahead to step 2:
75 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 75

Let's proceed to step 3:
When dividing 115 by 75, we get 1 with a remainder of 40.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 75 from 115 and we're left with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 75

On to step 4:
402 divided by 75 is 5 with a remainder of 27.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 27 after subtracting 375 from 402.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 75

Advancing to step 5:
If we divide 270 by 75, we get 3 and a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 153.0
If we subtract 225 from 270, we get 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 75

On to step 6:
When dividing 453 by 75, we get 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 1536.0
Deduct 450 from 453 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
75 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1536.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 75 fits into 300 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 1536.04
If we subtract 300 from 300, we get 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 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1536.04
The remainder is 0 after subtracting 0 from 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 10:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1536.04
Subtract 0 from 0 to get 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 1536.04 and a remainder of 0.0.
