561307 ÷ 68 
The aim is to understand the frequency of 68 in 561307.

Advancing to step 1:
The number 68 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 68

Advancing to step 2:
When dividing 56 by 68, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (1) from the dividend and append it to 56, then repeat: 561 / 68

Step 3:
68 can be fit into 561 8 times, resulting in a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 544 from 561 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 68

Moving on to step 4:
173 divided by 68 is 2 with a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtracting 136 from 173 leaves us with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 68

Let's proceed to step 5:
370 divided by 68 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 825.0
If we subtract 340 from 370, we get 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 68

Advancing to step 6:
307 divided by 68 is 4 with a remainder of 35.
Write down 4 as next digit of the result. 
Result so far: 8254.0
The remainder is 35 after subtracting 272 from 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
The number 68 fits into 350 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 8254.5
The remainder is 10 after subtracting 340 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 68, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 8254.51
If we take 68 away from 100, we end up 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:
68 can be fit into 320 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8254.514
If we take 272 away from 320, we end up 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.

Step 10:
The number 68 fits into 480 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 8254.5147
Subtract 476 from 480 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.

Let's proceed to step 11:
If we divide 40 by 68, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8254.5147
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 12:
When dividing 400 by 68, we get 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 8254.514705
Subtract 340 from 400 to 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.

On to step 13:
The number 68 fits into 600 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8254.5147058
Subtracting 544 from 600 leaves us 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.

Step 14:
When dividing 560 by 68, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8254.51470588
Subtract 544 from 560 to get 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 8254.51470588 with a remainder of 1.6e-08.
