Let's divide 471984 by 87
The aim is to understand the frequency of 87 in 471984.

Going ahead to step 1:
If we divide 4 by 87, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 87

Moving on to step 2:
87 goes into 47 0 times with a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Bring next digit (1) of the dividend behind the 47 and repeat the process: 471 / 87

Going ahead to step 3:
87 can be fit into 471 5 times, resulting in a remainder of 36.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 435 from 471 to get 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 87

Let's proceed to step 4:
When dividing 369 by 87, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 348 from 369, we get 21.
Include the next digit (8) from the dividend after 21, then repeat: 218 / 87

Advancing to step 5:
When dividing 218 by 87, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
Subtract 174 from 218 to get 44.
Append the next digit (4) from the dividend to 44 and continue with: 444 / 87

On to step 6:
If we divide 444 by 87, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5425.0
Subtracting 435 from 444 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 87, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 5425.1
If we subtract 87 from 90, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
When dividing 30 by 87, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 5425.1
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
87 goes into 300 3 times with a remainder of 39.
The next digit of our result is 3. 
Result so far: 5425.103
Subtract 261 from 300 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 10:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 5425.1034
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 5425.10344
Subtracting 348 from 420 leaves us 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 final outcome is 5425.10344, with a leftover of 7.2e-05.
