998575 ÷ 87 
The aim is to understand the frequency of 87 in 998575.

Moving on to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 87

Moving on to step 2:
99 divided by 87 is 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 87 from 99.
Take the next digit (8) from the dividend and append it to 12, then repeat: 128 / 87

Going ahead to step 3:
If we divide 128 by 87, we get 1 and a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 87 away from 128, we end up with 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 87

Step 4:
The number 87 fits into 415 4 times, leaving a remainder of 67.
The next digit of our result is 4. 
Result so far: 114.0
Subtracting 348 from 415 leaves us with 67.
Take the next digit (7) from the dividend and append it to 67, then repeat: 677 / 87

Advancing to step 5:
When dividing 677 by 87, we get 7 with a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 1147.0
Deduct 609 from 677 and we're left with 68.
Grab the next digit (5) from the dividend, add it to 68, then carry on: 685 / 87

Moving on to step 6:
685 divided by 87 is 7 with a remainder of 76.
Record the quotient 7 as the next digit in the result. 
Result so far: 11477.0
Subtracting 609 from 685 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 7:
When dividing 760 by 87, we get 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 11477.8
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
If we divide 640 by 87, we get 7 and a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 11477.87
Deduct 609 from 640 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
If we divide 310 by 87, we get 3 and a remainder of 49.
Use 3 as the next digit of our solution. 
Result so far: 11477.873
Deduct 261 from 310 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
When dividing 490 by 87, we get 5 with a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11477.8735
If we take 435 away from 490, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
When dividing 550 by 87, we get 6 with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 11477.87356
Subtract 522 from 550 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
87 can be fit into 280 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 11477.873563
If we subtract 261 from 280, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
If we divide 190 by 87, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 11477.8735632
If we take 174 away from 190, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 14:
160 divided by 87 is 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 11477.87356321
If we take 87 away from 160, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

In conclusion, the division gives 11477.87356321 with a balance of 7.3e-08.
