We look at the division of 98935153 by 87 
The aim is to understand the frequency of 87 in 98935153.

Going ahead to step 1:
87 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 87

Let's proceed to step 2:
87 goes into 98 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 11 after subtracting 87 from 98.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 87

On to step 3:
87 goes into 119 1 times with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 87 away from 119, we end up with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 87

On to step 4:
When dividing 323 by 87, we get 3 with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 113.0
If we subtract 261 from 323, we get 62.
Append the next digit (5) from the dividend to 62 and continue with: 625 / 87

Step 5:
87 can be fit into 625 7 times, resulting in a remainder of 16.
Write down 7 as next digit of the result. 
Result so far: 1137.0
If we subtract 609 from 625, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 87

Advancing to step 6:
87 goes into 161 1 times with a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 11371.0
Subtracting 87 from 161 leaves us with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 87

Advancing to step 7:
When dividing 745 by 87, we get 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 113718.0
If we take 696 away from 745, we end up with 49.
Fetch the next digit (3) from the dividend, attach it to 49 and continue: 493 / 87

Step 8:
87 goes into 493 5 times with a remainder of 58.
The number 5 becomes the next digit in our result. 
Result so far: 1137185.0
Subtracting 435 from 493 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 9:
87 can be fit into 580 6 times, resulting in a remainder of 58.
Write down 6 as next digit of the result. 
Result so far: 1137185.6
The remainder is 58 after subtracting 522 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
87 can be fit into 580 6 times, resulting in a remainder of 58.
The number 6 becomes the next digit in our result. 
Result so far: 1137185.66
Subtracting 522 from 580 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

After the division, we end up with 1137185.66 and a remainder of 0.058.
