830394 ÷ 75 
The aim is to understand the frequency of 75 in 830394.

Step 1:
75 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 75

Advancing to step 2:
When dividing 83 by 75, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 83, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 75

Moving on to step 3:
75 can be fit into 80 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 75 from 80 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 75

Moving on to step 4:
The number 75 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 110.0
The remainder is 53 after subtracting 0 from 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 75

Advancing to step 5:
When dividing 539 by 75, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 1107.0
If we take 525 away from 539, we end up with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 75

Step 6:
75 goes into 144 1 times with a remainder of 69.
The next digit of our result is 1. 
Result so far: 11071.0
If we take 75 away from 144, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
If we divide 690 by 75, we get 9 and a remainder of 15.
The next digit of our result is 9. 
Result so far: 11071.9
The remainder is 15 after subtracting 675 from 690.
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:
75 can be fit into 150 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 11071.92
Subtracting 150 from 150 leaves us 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.

Advancing to step 9:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11071.92
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.

Going ahead to step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 11071.92
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.

After the division, we end up with 11071.92 and a remainder of 0.0.
