508203 ÷ 87 
The aim is to understand the frequency of 87 in 508203.

Let's proceed to step 1:
87 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 87

Going ahead to step 2:
The number 87 fits into 50 0 times, leaving a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 87

Moving on to step 3:
When dividing 508 by 87, we get 5 with a remainder of 73.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 435 away from 508, we end up with 73.
Bring next digit (2) of the dividend behind the 73 and repeat the process: 732 / 87

Moving on to step 4:
When dividing 732 by 87, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 58.0
Deduct 696 from 732 and we're left with 36.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 87

On to step 5:
87 can be fit into 360 4 times, resulting in a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 584.0
If we take 348 away from 360, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 87

On to step 6:
87 goes into 123 1 times with a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 5841.0
Deduct 87 from 123 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
87 goes into 360 4 times with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 5841.4
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
87 goes into 120 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 5841.41
If we subtract 87 from 120, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
The number 87 fits into 330 3 times, leaving a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 5841.413
The remainder is 69 after subtracting 261 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
690 divided by 87 is 7 with a remainder of 81.
Record the quotient 7 as the next digit in the result. 
Result so far: 5841.4137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 11:
810 divided by 87 is 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 5841.41379
Subtracting 783 from 810 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
When dividing 270 by 87, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 5841.413793
Subtract 261 from 270 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
87 can be fit into 90 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 5841.4137931
Subtract 87 from 90 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 14:
87 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 5841.4137931
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 5841.4137931 with a balance of 3e-08.
