We're dividing 571184 by 87 
The aim is to understand the frequency of 87 in 571184.

Advancing to step 1:
The number 87 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 87

Advancing to step 2:
87 goes into 57 0 times with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (1) from the dividend, add it to 57, then carry on: 571 / 87

Step 3:
The number 87 fits into 571 6 times, leaving a remainder of 49.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 522 from 571 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 87

Step 4:
When dividing 491 by 87, we get 5 with a remainder of 56.
The next digit of our result is 5. 
Result so far: 65.0
If we take 435 away from 491, we end up with 56.
Append the next digit (8) from the dividend to 56 and continue with: 568 / 87

Advancing to step 5:
If we divide 568 by 87, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 656.0
The remainder is 46 after subtracting 522 from 568.
Append the next digit (4) from the dividend to 46 and continue with: 464 / 87

Moving on to step 6:
When dividing 464 by 87, we get 5 with a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 6565.0
If we take 435 away from 464, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
290 divided by 87 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 6565.3
If we take 261 away from 290, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 8:
290 divided by 87 is 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 6565.33
Subtracting 261 from 290 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

After the division, we end up with 6565.33 and a remainder of 0.029.
