Let's divide 16561542 by 75
The aim is to understand the frequency of 75 in 16561542.

On to step 1:
When dividing 1 by 75, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 75

Step 2:
75 can be fit into 16 0 times, resulting in a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 75

Going ahead to step 3:
75 goes into 165 2 times with a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 150 from 165 to get 15.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 75

Step 4:
The number 75 fits into 156 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 22.0
If we subtract 150 from 156, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 75

Advancing to step 5:
When dividing 61 by 75, we get 0 with a remainder of 61.
Write down 0 as next digit of the result. 
Result so far: 220.0
If we subtract 0 from 61, we get 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 75

Moving on to step 6:
If we divide 615 by 75, we get 8 and a remainder of 15.
The next digit of our result is 8. 
Result so far: 2208.0
The remainder is 15 after subtracting 600 from 615.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 75

On to step 7:
The number 75 fits into 154 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 22082.0
Deduct 150 from 154 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 75

Moving on to step 8:
42 divided by 75 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 220820.0
Subtracting 0 from 42 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 9:
When dividing 420 by 75, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 220820.5
Deduct 375 from 420 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
75 goes into 450 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 220820.56
Subtract 450 from 450 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.

Going ahead to step 11:
75 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 220820.56
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.

Moving on to step 12:
When dividing 0 by 75, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 220820.56
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.

The quotient of the division is 220820.56, and the remainder is 0.0.
