We're dividing 824968 by 68 
The aim is to understand the frequency of 68 in 824968.

On to step 1:
When dividing 8 by 68, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 68

Step 2:
82 divided by 68 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 68 from 82 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 68

Let's proceed to step 3:
68 goes into 144 2 times with a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 8 after subtracting 136 from 144.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 68

On to step 4:
68 can be fit into 89 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
If we subtract 68 from 89, we get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 68

Advancing to step 5:
The number 68 fits into 216 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 1213.0
Subtract 204 from 216 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 68

On to step 6:
128 divided by 68 is 1 with a remainder of 60.
The next digit of our result is 1. 
Result so far: 12131.0
Deduct 68 from 128 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.

On to step 7:
600 divided by 68 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 12131.8
Deduct 544 from 600 and we're left 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.

Step 8:
If we divide 560 by 68, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 12131.88
If we take 544 away from 560, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 12131.88 and a remainder of 0.016.
