We look at the division of 911648 by 68 
The aim is to understand the frequency of 68 in 911648.

Let's proceed to step 1:
9 divided by 68 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 68

Going ahead to step 2:
68 goes into 91 1 times with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 68 from 91 and we're left with 23.
Append the next digit (1) from the dividend to 23 and continue with: 231 / 68

Moving on to step 3:
68 goes into 231 3 times with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 204 away from 231, we end up with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 68

On to step 4:
68 can be fit into 276 4 times, resulting in a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Subtracting 272 from 276 leaves us with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 68

Advancing to step 5:
The number 68 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 1340.0
If we subtract 0 from 44, we get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 68

Moving on to step 6:
448 divided by 68 is 6 with a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 13406.0
The remainder is 40 after subtracting 408 from 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
68 goes into 400 5 times with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 13406.5
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
If we divide 600 by 68, we get 8 and a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 13406.58
Subtracting 544 from 600 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
68 goes into 560 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 13406.588
Subtract 544 from 560 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 13406.588 with a remaining 0.0016.
