We look at the division of 472377 by 87 
The aim is to understand the frequency of 87 in 472377.

Going ahead to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 87

Let's proceed to step 2:
87 goes into 47 0 times with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Include the next digit (2) from the dividend after 47, then repeat: 472 / 87

Let's proceed to step 3:
87 can be fit into 472 5 times, resulting in a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 435 from 472, we get 37.
Take the next digit (3) from the dividend and append it to 37, then repeat: 373 / 87

Advancing to step 4:
The number 87 fits into 373 4 times, leaving a remainder of 25.
The next digit of our result is 4. 
Result so far: 54.0
If we subtract 348 from 373, we get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 87

Moving on to step 5:
87 goes into 257 2 times with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 542.0
The remainder is 83 after subtracting 174 from 257.
Grab the next digit (7) from the dividend, add it to 83, then carry on: 837 / 87

On to step 6:
837 divided by 87 is 9 with a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 5429.0
Subtracting 783 from 837 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 7:
The number 87 fits into 540 6 times, leaving a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 5429.6
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
87 can be fit into 180 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 5429.62
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
87 can be fit into 60 0 times, resulting in a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5429.62
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
87 can be fit into 600 6 times, resulting in a remainder of 78.
The next digit of our result is 6. 
Result so far: 5429.6206
If we subtract 522 from 600, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 11:
When dividing 780 by 87, we get 8 with a remainder of 84.
The next digit of our result is 8. 
Result so far: 5429.62068
If we subtract 696 from 780, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 12:
840 divided by 87 is 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 5429.620689
If we take 783 away from 840, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
87 goes into 570 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 5429.6206896
Subtracting 522 from 570 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
87 goes into 480 5 times with a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 5429.62068965
If we subtract 435 from 480, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 5429.62068965 with a remainder of 4.5e-08.
