987001 ÷ 87 
The aim is to understand the frequency of 87 in 987001.

Moving on to step 1:
If we divide 9 by 87, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 87

Step 2:
When dividing 98 by 87, we get 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 87 from 98, we get 11.
Include the next digit (7) from the dividend after 11, then repeat: 117 / 87

Going ahead to step 3:
87 can be fit into 117 1 times, resulting in a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 87 from 117, we get 30.
Fetch the next digit (0) from the dividend, attach it to 30 and continue: 300 / 87

Moving on to step 4:
87 goes into 300 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtract 261 from 300 to get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 87

On to step 5:
If we divide 390 by 87, we get 4 and a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 1134.0
The remainder is 42 after subtracting 348 from 390.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 87

On to step 6:
87 goes into 421 4 times with a remainder of 73.
Use 4 as the next digit of our solution. 
Result so far: 11344.0
If we subtract 348 from 421, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 7:
The number 87 fits into 730 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 11344.8
If we take 696 away from 730, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
87 can be fit into 340 3 times, resulting in a remainder of 79.
The number 3 becomes the next digit in our result. 
Result so far: 11344.83
Subtracting 261 from 340 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
When dividing 790 by 87, we get 9 with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 11344.839
If we take 783 away from 790, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
70 divided by 87 is 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 11344.839
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 87, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11344.83908
Subtracting 696 from 700 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 12:
40 divided by 87 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 11344.83908
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 87, we get 4 and a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 11344.8390804
Deduct 348 from 400 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
If we divide 520 by 87, we get 5 and a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 11344.83908045
If we subtract 435 from 520, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 11344.83908045 and a remainder of 8.5e-08.
