We're dividing 73986 by 75 
The aim is to understand the frequency of 75 in 73986.

Let's proceed to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 75

Advancing to step 2:
75 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 75

Step 3:
If we divide 739 by 75, we get 9 and a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 675 from 739 to get 64.
Append the next digit (8) from the dividend to 64 and continue with: 648 / 75

On to step 4:
When dividing 648 by 75, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 98.0
If we take 600 away from 648, we end up with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 75

Advancing to step 5:
The number 75 fits into 486 6 times, leaving a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 986.0
Deduct 450 from 486 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 6:
The number 75 fits into 360 4 times, leaving a remainder of 60.
The next digit of our result is 4. 
Result so far: 986.4
Subtract 300 from 360 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 7:
If we divide 600 by 75, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 986.48
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.

Let's proceed to step 8:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 986.48
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.

Moving on to step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 986.48
If we take 0 away from 0, 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.

After the division, we end up with 986.48 and a remainder of 0.0.
