38772304 ÷ 75 
The aim is to understand the frequency of 75 in 38772304.

On to step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 75

Advancing to step 2:
75 goes into 38 0 times with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Bring next digit (7) of the dividend behind the 38 and repeat the process: 387 / 75

Let's proceed to step 3:
75 goes into 387 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 375 from 387 to get 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 75

Going ahead to step 4:
127 divided by 75 is 1 with a remainder of 52.
The next digit of our result is 1. 
Result so far: 51.0
Deduct 75 from 127 and we're left with 52.
Include the next digit (2) from the dividend after 52, then repeat: 522 / 75

Let's proceed to step 5:
75 can be fit into 522 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 516.0
The remainder is 72 after subtracting 450 from 522.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 75

Advancing to step 6:
If we divide 723 by 75, we get 9 and a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 5169.0
Subtract 675 from 723 to get 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 75

On to step 7:
If we divide 480 by 75, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 51696.0
Subtracting 450 from 480 leaves us with 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 75

On to step 8:
75 can be fit into 304 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 516964.0
Subtracting 300 from 304 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
75 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 516964.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
If we divide 400 by 75, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 516964.05
Deduct 375 from 400 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 11:
When dividing 250 by 75, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 516964.053
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 516964.0533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 516964.0533, and the remainder is 0.00025.
