578953 divided by 68 
The aim is to understand the frequency of 68 in 578953.

Moving on to step 1:
5 divided by 68 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 68

Moving on to step 2:
57 divided by 68 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 68

Going ahead to step 3:
The number 68 fits into 578 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 544 from 578 to get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 68

Going ahead to step 4:
68 can be fit into 349 5 times, resulting in a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
The remainder is 9 after subtracting 340 from 349.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 68

Moving on to step 5:
68 can be fit into 95 1 times, resulting in a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 851.0
Subtracting 68 from 95 leaves us with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 68

Going ahead to step 6:
68 can be fit into 273 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 8514.0
If we subtract 272 from 273, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
68 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8514.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 68 is 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 8514.01
Subtracting 68 from 100 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.

Let's proceed to step 9:
If we divide 320 by 68, we get 4 and a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 8514.014
Deduct 272 from 320 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 68 fits into 480 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 8514.0147
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.

Step 11:
68 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 8514.0147
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
The number 68 fits into 400 5 times, leaving a remainder of 60.
The next digit of our result is 5. 
Result so far: 8514.014705
If we subtract 340 from 400, we get 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 13:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 8514.0147058
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.

Moving on to step 14:
The number 68 fits into 560 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8514.01470588
The remainder is 16 after subtracting 544 from 560.
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 8514.01470588 with a remainder of 1.6e-08.
