Let's divide 962397 by 87
The aim is to understand the frequency of 87 in 962397.

Going ahead to step 1:
When dividing 9 by 87, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 87

Going ahead to step 2:
87 can be fit into 96 1 times, resulting in a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 87 from 96 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 87

Advancing to step 3:
When dividing 92 by 87, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 87 from 92 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 87

Going ahead to step 4:
53 divided by 87 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtract 0 from 53 to get 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 87

Advancing to step 5:
539 divided by 87 is 6 with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
If we subtract 522 from 539, we get 17.
Bring next digit (7) of the dividend behind the 17 and repeat the process: 177 / 87

Let's proceed to step 6:
87 can be fit into 177 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 11062.0
Subtract 174 from 177 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 7:
30 divided by 87 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 11062.0
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.

Advancing to step 8:
The number 87 fits into 300 3 times, leaving a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 11062.03
Subtracting 261 from 300 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
87 goes into 390 4 times with a remainder of 42.
The next digit of our result is 4. 
Result so far: 11062.034
Deduct 348 from 390 and we're left 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.

On to step 10:
87 can be fit into 420 4 times, resulting in a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 11062.0344
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 11062.0344 with a remaining 0.00072.
