539255 ÷ 74 
The aim is to understand the frequency of 74 in 539255.

Let's proceed to step 1:
The number 74 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 74

Moving on to step 2:
The number 74 fits into 53 0 times, leaving a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 74

Step 3:
The number 74 fits into 539 7 times, leaving a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 518 from 539 to get 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 74

Advancing to step 4:
The number 74 fits into 212 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 72.0
If we subtract 148 from 212, we get 64.
Take the next digit (5) from the dividend and append it to 64, then repeat: 645 / 74

Going ahead to step 5:
74 goes into 645 8 times with a remainder of 53.
Record the quotient 8 as the next digit in the result. 
Result so far: 728.0
If we subtract 592 from 645, we get 53.
Include the next digit (5) from the dividend after 53, then repeat: 535 / 74

Going ahead to step 6:
The number 74 fits into 535 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 7287.0
If we subtract 518 from 535, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
74 can be fit into 170 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 7287.2
If we take 148 away from 170, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
220 divided by 74 is 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 7287.22
Deduct 148 from 220 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 7287.22, and the remainder is 0.072.
