96519446 ÷ 75 
The aim is to understand the frequency of 75 in 96519446.

Advancing to step 1:
The number 75 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 75

Step 2:
75 goes into 96 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 75 from 96 and we're left with 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 75

Step 3:
If we divide 215 by 75, we get 2 and a remainder of 65.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 65 after subtracting 150 from 215.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 75

Let's proceed to step 4:
The number 75 fits into 651 8 times, leaving a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
Subtracting 600 from 651 leaves us with 51.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 75

Let's proceed to step 5:
75 can be fit into 519 6 times, resulting in a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 1286.0
If we take 450 away from 519, we end up with 69.
Bring next digit (4) of the dividend behind the 69 and repeat the process: 694 / 75

On to step 6:
75 can be fit into 694 9 times, resulting in a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 12869.0
Subtract 675 from 694 to get 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 75

Advancing to step 7:
194 divided by 75 is 2 with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 128692.0
The remainder is 44 after subtracting 150 from 194.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 75

Step 8:
75 can be fit into 446 5 times, resulting in a remainder of 71.
Use 5 as the next digit of our solution. 
Result so far: 1286925.0
Deduct 375 from 446 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
When dividing 710 by 75, we get 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 1286925.9
If we subtract 675 from 710, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
If we divide 350 by 75, we get 4 and a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 1286925.94
If we subtract 300 from 350, 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.

Step 11:
When dividing 500 by 75, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286925.946
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.

On to step 12:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 1286925.9466
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.

The final result is 1286925.9466 with a remainder of 0.0005.
