899144 divided by 87 
The aim is to understand the frequency of 87 in 899144.

Let's proceed to step 1:
When dividing 8 by 87, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 87

Moving on to step 2:
When dividing 89 by 87, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 87 away from 89, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 87

Step 3:
The number 87 fits into 29 0 times, leaving a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 87

Step 4:
87 can be fit into 291 3 times, resulting in a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 261 from 291 leaves us with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 87

On to step 5:
87 goes into 304 3 times with a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 1033.0
Subtract 261 from 304 to get 43.
Fetch the next digit (4) from the dividend, attach it to 43 and continue: 434 / 87

Step 6:
434 divided by 87 is 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 10334.0
If we take 348 away from 434, we end up 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.

Going ahead to step 7:
The number 87 fits into 860 9 times, leaving a remainder of 77.
Record the quotient 9 as the next digit in the result. 
Result so far: 10334.9
If we subtract 783 from 860, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 8:
When dividing 770 by 87, we get 8 with a remainder of 74.
Use 8 as the next digit of our solution. 
Result so far: 10334.98
The remainder is 74 after subtracting 696 from 770.
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:
The number 87 fits into 740 8 times, leaving a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 10334.988
Deduct 696 from 740 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.

In conclusion, the division gives 10334.988 with a balance of 0.0044.
