We're dividing 8872 by 87 
The aim is to understand the frequency of 87 in 8872.

On to step 1:
87 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 87

On to step 2:
87 goes into 88 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 87 from 88 and we're left with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 87

Going ahead to step 3:
87 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 87

Going ahead to step 4:
87 goes into 172 1 times with a remainder of 85.
The next digit of our result is 1. 
Result so far: 101.0
Deduct 87 from 172 and we're left 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.

Moving on to step 5:
850 divided by 87 is 9 with a remainder of 67.
Write down 9 as next digit of the result. 
Result so far: 101.9
If we take 783 away from 850, we end up 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.

Advancing to step 6:
87 goes into 670 7 times with a remainder of 61.
The next digit of our result is 7. 
Result so far: 101.97
If we take 609 away from 670, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 7:
If we divide 610 by 87, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 101.977
Subtracting 609 from 610 leaves us 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.

In conclusion, the division gives 101.977 with a balance of 0.0001.
