158784 ÷ 75 
The aim is to understand the frequency of 75 in 158784.

On to step 1:
1 divided by 75 is 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.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 75

Step 2:
When dividing 15 by 75, we get 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 75

Step 3:
The number 75 fits into 158 2 times, leaving a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 8 after subtracting 150 from 158.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 75

Step 4:
75 goes into 87 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 75 away from 87, we end up with 12.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 75

Let's proceed to step 5:
75 goes into 128 1 times with a remainder of 53.
The next digit of our result is 1. 
Result so far: 211.0
Subtract 75 from 128 to get 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 75

Advancing to step 6:
75 goes into 534 7 times with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 2117.0
The remainder is 9 after subtracting 525 from 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
75 can be fit into 90 1 times, resulting in a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 2117.1
The remainder is 15 after subtracting 75 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 75, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2117.12
If we take 150 away from 150, 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.

Step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2117.12
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 10:
When dividing 0 by 75, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2117.12
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 2117.12 and a remainder of 0.0.
