578590 divided by 68 
The aim is to understand the frequency of 68 in 578590.

Going ahead to step 1:
5 divided by 68 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 68

On to step 2:
The number 68 fits into 57 0 times, leaving a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 68

Moving on to step 3:
578 divided by 68 is 8 with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 544 from 578 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 68

Advancing to step 4:
68 can be fit into 345 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
If we take 340 away from 345, we end up with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 68

Going ahead to step 5:
If we divide 59 by 68, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
If we take 0 away from 59, we end up with 59.
Grab the next digit (0) from the dividend, add it to 59, then carry on: 590 / 68

On to step 6:
If we divide 590 by 68, we get 8 and a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 8508.0
Deduct 544 from 590 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
68 goes into 460 6 times with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 8508.6
Deduct 408 from 460 and we're left 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.

On to step 8:
68 goes into 520 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 8508.67
Deduct 476 from 520 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
When dividing 440 by 68, we get 6 with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 8508.676
Subtracting 408 from 440 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
68 goes into 320 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 8508.6764
If we subtract 272 from 320, 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.

Advancing to step 11:
68 can be fit into 480 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 8508.67647
The remainder is 4 after subtracting 476 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
68 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8508.67647
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
400 divided by 68 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 8508.6764705
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.

Let's proceed to step 14:
The number 68 fits into 600 8 times, leaving a remainder of 56.
The next digit of our result is 8. 
Result so far: 8508.67647058
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.

In conclusion, the division gives 8508.67647058 with a balance of 5.6e-08.
