802902 divided by 87 
The aim is to understand the frequency of 87 in 802902.

Step 1:
If we divide 8 by 87, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 87

Step 2:
The number 87 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 87

Going ahead to step 3:
The number 87 fits into 802 9 times, leaving a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 19 after subtracting 783 from 802.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 87

Let's proceed to step 4:
199 divided by 87 is 2 with a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
If we subtract 174 from 199, we get 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 87

Step 5:
87 can be fit into 250 2 times, resulting in a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 922.0
Subtract 174 from 250 to get 76.
Bring next digit (2) of the dividend behind the 76 and repeat the process: 762 / 87

Going ahead to step 6:
762 divided by 87 is 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 9228.0
Deduct 696 from 762 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 7:
87 can be fit into 660 7 times, resulting in a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 9228.7
If we take 609 away from 660, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 8:
510 divided by 87 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 9228.75
If we take 435 away from 510, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
750 divided by 87 is 8 with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 9228.758
Subtracting 696 from 750 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
540 divided by 87 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 9228.7586
Subtract 522 from 540 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 87, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 9228.75862
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 87 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 9228.75862
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
If we divide 600 by 87, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 9228.7586206
Subtract 522 from 600 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
When dividing 780 by 87, we get 8 with a remainder of 84.
Record the quotient 8 as the next digit in the result. 
Result so far: 9228.75862068
The remainder is 84 after subtracting 696 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Our division results in 9228.75862068 with a remaining 8.4e-08.
