We divide 870807 by 87
The aim is to understand the frequency of 87 in 870807.

Step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 87

Step 2:
87 can be fit into 87 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 87 from 87 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 87

Advancing to step 3:
0 divided by 87 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 87

Moving on to step 4:
When dividing 8 by 87, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 87

Going ahead to step 5:
When dividing 80 by 87, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
If we subtract 0 from 80, we get 80.
Include the next digit (7) from the dividend after 80, then repeat: 807 / 87

Moving on to step 6:
87 can be fit into 807 9 times, resulting in a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 10009.0
Subtract 783 from 807 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 87, we get 2 with a remainder of 66.
Use 2 as the next digit of our solution. 
Result so far: 10009.2
If we take 174 away from 240, we end up 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.

Going ahead to step 8:
If we divide 660 by 87, we get 7 and a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 10009.27
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.

Step 9:
87 goes into 510 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 10009.275
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.

Moving on to step 10:
If we divide 750 by 87, we get 8 and a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 10009.2758
Subtract 696 from 750 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 11:
87 can be fit into 540 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 10009.27586
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
87 can be fit into 180 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 10009.275862
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 13:
87 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 10009.275862
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 14:
600 divided by 87 is 6 with a remainder of 78.
Put 6 as the next digit of the answer. 
Result so far: 10009.27586206
If we take 522 away from 600, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 10009.27586206 with a balance of 7.8e-08.
