516940 divided by 68 
The aim is to understand the frequency of 68 in 516940.

Going ahead 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.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 68

Moving on to step 2:
If we divide 51 by 68, we get 0 and a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Append the next digit (6) from the dividend to 51 and continue with: 516 / 68

Let's proceed to step 3:
516 divided by 68 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 476 away from 516, we end up with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 68

Advancing to step 4:
68 goes into 409 6 times with a remainder of 1.
The next digit of our result is 6. 
Result so far: 76.0
Subtract 408 from 409 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 68

On to step 5:
If we divide 14 by 68, we get 0 and a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 760.0
Subtracting 0 from 14 leaves us with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 68

Going ahead to step 6:
The number 68 fits into 140 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7602.0
Subtract 136 from 140 to get 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 7:
When dividing 40 by 68, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7602.0
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.

Moving on to step 8:
400 divided by 68 is 5 with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 7602.05
Subtracting 340 from 400 leaves us 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.

Step 9:
600 divided by 68 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 7602.058
If we take 544 away from 600, we end up 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.

Going ahead to step 10:
When dividing 560 by 68, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7602.0588
Deduct 544 from 560 and we're left 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 7602.0588 and a remainder of 0.00016.
