943950 ÷ 75 
The aim is to understand the frequency of 75 in 943950.

Going ahead to step 1:
75 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 75

Advancing to step 2:
If we divide 94 by 75, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 75 from 94 to get 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 75

Step 3:
When dividing 193 by 75, we get 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 150 from 193, we get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 75

Let's proceed to step 4:
The number 75 fits into 439 5 times, leaving a remainder of 64.
The next digit of our result is 5. 
Result so far: 125.0
If we take 375 away from 439, we end up with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 75

On to step 5:
If we divide 645 by 75, we get 8 and a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 1258.0
Deduct 600 from 645 and we're left with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 75

Going ahead to step 6:
75 goes into 450 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 12586.0
The remainder is 0 after subtracting 450 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12586.0
If we subtract 0 from 0, 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.

Let's proceed to step 8:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12586.0
If we subtract 0 from 0, 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.

After the division, we end up with 12586.0 and a remainder of 0.0.
