We look at the division of 984348 by 87 
The aim is to understand the frequency of 87 in 984348.

Advancing to step 1:
The number 87 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 87

Moving on to step 2:
98 divided by 87 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 87 away from 98, we end up with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 87

Let's proceed to step 3:
If we divide 114 by 87, we get 1 and a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 87 from 114 and we're left with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 87

Going ahead to step 4:
87 goes into 273 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 113.0
Subtracting 261 from 273 leaves us with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 87

Advancing to step 5:
87 can be fit into 124 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1131.0
The remainder is 37 after subtracting 87 from 124.
Append the next digit (8) from the dividend to 37 and continue with: 378 / 87

Going ahead to step 6:
When dividing 378 by 87, we get 4 with a remainder of 30.
The next digit of our result is 4. 
Result so far: 11314.0
If we subtract 348 from 378, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
87 goes into 300 3 times with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 11314.3
The remainder is 39 after subtracting 261 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
When dividing 390 by 87, we get 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 11314.34
If we take 348 away from 390, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
87 goes into 420 4 times with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 11314.344
If we subtract 348 from 420, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 11314.344 with a remaining 0.0072.
