618688 divided by 68 
The aim is to understand the frequency of 68 in 618688.

Going ahead to step 1:
68 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 68

On to step 2:
When dividing 61 by 68, we get 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 61, we get 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 68

Step 3:
618 divided by 68 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 612 from 618 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 68

Step 4:
68 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 68

Moving on to step 5:
When dividing 668 by 68, we get 9 with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 909.0
If we subtract 612 from 668, we get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 68

Let's proceed to step 6:
68 can be fit into 568 8 times, resulting in a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 9098.0
The remainder is 24 after subtracting 544 from 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
68 can be fit into 240 3 times, resulting in a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 9098.3
Subtract 204 from 240 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
68 goes into 360 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 9098.35
Deduct 340 from 360 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 68 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 9098.352
The remainder is 64 after subtracting 136 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 10:
The number 68 fits into 640 9 times, leaving a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 9098.3529
Subtracting 612 from 640 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
If we divide 280 by 68, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 9098.35294
Subtracting 272 from 280 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
When dividing 80 by 68, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 9098.352941
Deduct 68 from 80 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 13:
If we divide 120 by 68, we get 1 and a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 9098.3529411
If we subtract 68 from 120, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 9098.3529411 with a remaining 5.2e-07.
