We look at the division of 83105465 by 87 
The aim is to understand the frequency of 87 in 83105465.

Going ahead to step 1:
8 divided by 87 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 87

On to step 2:
When dividing 83 by 87, we get 0 with a remainder of 83.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (1) from the dividend, add it to 83, then carry on: 831 / 87

Going ahead to step 3:
831 divided by 87 is 9 with a remainder of 48.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 783 from 831 leaves us with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 87

Advancing to step 4:
The number 87 fits into 480 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 435 from 480 and we're left with 45.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 87

On to step 5:
87 can be fit into 455 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 955.0
Subtracting 435 from 455 leaves us with 20.
Grab the next digit (4) from the dividend, add it to 20, then carry on: 204 / 87

Step 6:
204 divided by 87 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 9552.0
If we subtract 174 from 204, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 87

Let's proceed to step 7:
306 divided by 87 is 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 95523.0
If we take 261 away from 306, we end up with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 87

Moving on to step 8:
When dividing 455 by 87, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 955235.0
The remainder is 20 after subtracting 435 from 455.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
87 goes into 200 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 955235.2
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
When dividing 260 by 87, we get 2 with a remainder of 86.
Record the quotient 2 as the next digit in the result. 
Result so far: 955235.22
Subtracting 174 from 260 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

In conclusion, the division gives 955235.22 with a balance of 0.086.
