We look at the division of 725846 by 68 
The aim is to understand the frequency of 68 in 725846.

Advancing to step 1:
If we divide 7 by 68, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 68

Going ahead to step 2:
68 goes into 72 1 times with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 68 from 72 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 68

Going ahead to step 3:
The number 68 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 45 after subtracting 0 from 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 68

Advancing to step 4:
458 divided by 68 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
Deduct 408 from 458 and we're left with 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 68

Moving on to step 5:
If we divide 504 by 68, we get 7 and a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 1067.0
Subtract 476 from 504 to get 28.
Append the next digit (6) from the dividend to 28 and continue with: 286 / 68

On to step 6:
The number 68 fits into 286 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 10674.0
If we subtract 272 from 286, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 68, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 10674.2
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 68, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 10674.2
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.

Step 9:
The number 68 fits into 400 5 times, leaving a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 10674.205
The remainder is 60 after subtracting 340 from 400.
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 10:
600 divided by 68 is 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 10674.2058
Subtract 544 from 600 to get 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 11:
If we divide 560 by 68, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 10674.20588
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.

After the division, we end up with 10674.20588 and a remainder of 1.6e-05.
