We're dividing 987941 by 87 
The aim is to understand the frequency of 87 in 987941.

Advancing to step 1:
87 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 87

Going ahead to step 2:
87 goes into 98 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 87 away from 98, we end up with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 87

Moving on to step 3:
If we divide 117 by 87, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 87 from 117 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 87

Going ahead to step 4:
When dividing 309 by 87, we get 3 with a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
The remainder is 48 after subtracting 261 from 309.
Take the next digit (4) from the dividend and append it to 48, then repeat: 484 / 87

Step 5:
87 can be fit into 484 5 times, resulting in a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 1135.0
The remainder is 49 after subtracting 435 from 484.
Bring next digit (1) of the dividend behind the 49 and repeat the process: 491 / 87

Let's proceed to step 6:
The number 87 fits into 491 5 times, leaving a remainder of 56.
The next digit of our result is 5. 
Result so far: 11355.0
If we subtract 435 from 491, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
87 can be fit into 560 6 times, resulting in a remainder of 38.
The next digit of our result is 6. 
Result so far: 11355.6
If we take 522 away from 560, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
87 goes into 380 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11355.64
If we take 348 away from 380, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 87, we get 3 with a remainder of 59.
The next digit of our result is 3. 
Result so far: 11355.643
Subtract 261 from 320 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 10:
87 goes into 590 6 times with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 11355.6436
Deduct 522 from 590 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
If we divide 680 by 87, we get 7 and a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 11355.64367
If we take 609 away from 680, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 12:
If we divide 710 by 87, we get 8 and a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 11355.643678
If we take 696 away from 710, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
140 divided by 87 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 11355.6436781
Subtract 87 from 140 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 14:
When dividing 530 by 87, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 11355.64367816
If we take 522 away from 530, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 11355.64367816 with a balance of 8e-09.
