481631 divided by 87 
The aim is to understand the frequency of 87 in 481631.

Let's proceed to step 1:
87 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 87

Moving on to step 2:
The number 87 fits into 48 0 times, leaving a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Append the next digit (1) from the dividend to 48 and continue with: 481 / 87

On to step 3:
481 divided by 87 is 5 with a remainder of 46.
The next digit of our result is 5. 
Result so far: 5.0
The remainder is 46 after subtracting 435 from 481.
Append the next digit (6) from the dividend to 46 and continue with: 466 / 87

Advancing to step 4:
87 goes into 466 5 times with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 435 from 466 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 87

Advancing to step 5:
If we divide 313 by 87, we get 3 and a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 553.0
Subtracting 261 from 313 leaves us with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 87

Step 6:
87 can be fit into 521 5 times, resulting in a remainder of 86.
Put 5 as the next digit of the answer. 
Result so far: 5535.0
Deduct 435 from 521 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 7:
If we divide 860 by 87, we get 9 and a remainder of 77.
The next digit of our result is 9. 
Result so far: 5535.9
If we take 783 away from 860, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 8:
The number 87 fits into 770 8 times, leaving a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 5535.98
Subtract 696 from 770 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
When dividing 740 by 87, we get 8 with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 5535.988
If we subtract 696 from 740, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 5535.988 with a balance of 0.0044.
