836230 divided by 75 
The aim is to understand the frequency of 75 in 836230.

On to step 1:
75 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 75

Step 2:
75 can be fit into 83 1 times, resulting in a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 75 from 83 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 75

Let's proceed to step 3:
If we divide 86 by 75, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 11.0
Deduct 75 from 86 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 75

On to step 4:
112 divided by 75 is 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
The remainder is 37 after subtracting 75 from 112.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 75

Step 5:
If we divide 373 by 75, we get 4 and a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 1114.0
Subtracting 300 from 373 leaves us with 73.
Append the next digit (0) from the dividend to 73 and continue with: 730 / 75

Advancing to step 6:
The number 75 fits into 730 9 times, leaving a remainder of 55.
Use 9 as the next digit of our solution. 
Result so far: 11149.0
Subtracting 675 from 730 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 7:
75 goes into 550 7 times with a remainder of 25.
Use 7 as the next digit of our solution. 
Result so far: 11149.7
Deduct 525 from 550 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.

Moving on to step 8:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11149.73
Deduct 225 from 250 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.

Advancing to step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 11149.733
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 11149.733, and the remainder is 0.0025.
