We're dividing 990516 by 68 
The aim is to understand the frequency of 68 in 990516.

Let's proceed to step 1:
The number 68 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 68

Going ahead to step 2:
If we divide 99 by 68, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 68 from 99 and we're left with 31.
Take the next digit (0) from the dividend and append it to 31, then repeat: 310 / 68

Going ahead to step 3:
The number 68 fits into 310 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 272 from 310 leaves us with 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 68

Let's proceed to step 4:
68 can be fit into 385 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 145.0
Deduct 340 from 385 and we're left with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 68

Going ahead to step 5:
If we divide 451 by 68, we get 6 and a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 1456.0
Subtract 408 from 451 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 68

Moving on to step 6:
68 can be fit into 436 6 times, resulting in a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 14566.0
Subtracting 408 from 436 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
280 divided by 68 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 14566.4
Subtract 272 from 280 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 14566.41
If we subtract 68 from 80, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
If we divide 120 by 68, we get 1 and a remainder of 52.
The next digit of our result is 1. 
Result so far: 14566.411
Subtracting 68 from 120 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 14566.411 with a remaining 0.0052.
