102886 divided by 87 
The aim is to understand the frequency of 87 in 102886.

Let's proceed to step 1:
87 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 87

Let's proceed to step 2:
The number 87 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 87

Step 3:
When dividing 102 by 87, we get 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 15 after subtracting 87 from 102.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 87

Advancing to step 4:
The number 87 fits into 158 1 times, leaving a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 87 from 158 leaves us with 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 87

Moving on to step 5:
718 divided by 87 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 696 from 718 and we're left with 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 87

Advancing to step 6:
The number 87 fits into 226 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 1182.0
Subtracting 174 from 226 leaves us 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.

Step 7:
87 goes into 520 5 times with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 1182.5
If we take 435 away from 520, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 8:
When dividing 850 by 87, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 1182.59
Deduct 783 from 850 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 9:
670 divided by 87 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 1182.597
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 10:
87 goes into 610 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1182.5977
Deduct 609 from 610 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final result is 1182.5977 with a remainder of 1e-05.
