We're dividing 285580 by 68 
The aim is to understand the frequency of 68 in 285580.

Let's proceed to step 1:
68 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 68

Step 2:
The number 68 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 68

Going ahead to step 3:
68 can be fit into 285 4 times, resulting in a remainder of 13.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 13 after subtracting 272 from 285.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 68

Advancing to step 4:
The number 68 fits into 135 1 times, leaving a remainder of 67.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 68 away from 135, we end up with 67.
Grab the next digit (8) from the dividend, add it to 67, then carry on: 678 / 68

Let's proceed to step 5:
When dividing 678 by 68, we get 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 419.0
If we subtract 612 from 678, we get 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 68

Moving on to step 6:
The number 68 fits into 660 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 4199.0
If we subtract 612 from 660, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
68 goes into 480 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 4199.7
Subtracting 476 from 480 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 68 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4199.7
If we subtract 0 from 40, we get 40.
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 9:
When dividing 400 by 68, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 4199.705
If we take 340 away from 400, we end up 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.

Moving on to step 10:
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: 4199.7058
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
68 goes into 560 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 4199.70588
Subtracting 544 from 560 leaves us 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.

The final result is 4199.70588 with a remainder of 1.6e-05.
