Let's divide 457287 by 71
The aim is to understand the frequency of 71 in 457287.

Step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 71

On to step 2:
The number 71 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 71

Moving on to step 3:
If we divide 457 by 71, we get 6 and a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 426 from 457, we get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 71

Advancing to step 4:
The number 71 fits into 312 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 64.0
Subtract 284 from 312 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 71

Let's proceed to step 5:
288 divided by 71 is 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 644.0
If we take 284 away from 288, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 71

Going ahead to step 6:
The number 71 fits into 47 0 times, leaving a remainder of 47.
The next digit of our result is 0. 
Result so far: 6440.0
The remainder is 47 after subtracting 0 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
If we divide 470 by 71, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6440.6
Deduct 426 from 470 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
The number 71 fits into 440 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6440.66
Subtracting 426 from 440 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 6440.66 and a remainder of 0.014.
