285333 divided by 71 
The aim is to understand the frequency of 71 in 285333.

Moving on to step 1:
When dividing 2 by 71, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 71

Advancing to step 2:
If we divide 28 by 71, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 71

Moving on to step 3:
If we divide 285 by 71, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 1 after subtracting 284 from 285.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 71

Step 4:
71 goes into 13 0 times with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 13, we end up with 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 71

Going ahead to step 5:
When dividing 133 by 71, we get 1 with a remainder of 62.
Write down 1 as next digit of the result. 
Result so far: 401.0
If we subtract 71 from 133, we get 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 71

Moving on to step 6:
71 goes into 623 8 times with a remainder of 55.
Write down 8 as next digit of the result. 
Result so far: 4018.0
If we subtract 568 from 623, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 7:
550 divided by 71 is 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 4018.7
Subtract 497 from 550 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
530 divided by 71 is 7 with a remainder of 33.
Put 7 as the next digit of the answer. 
Result so far: 4018.77
Subtracting 497 from 530 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

After the division, we end up with 4018.77 and a remainder of 0.033.
