We look at the division of 667486 by 68 
The aim is to understand the frequency of 68 in 667486.

Advancing to step 1:
68 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 68

Advancing to step 2:
If we divide 66 by 68, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 68

Moving on to step 3:
When dividing 667 by 68, we get 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 612 away from 667, we end up with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 68

Moving on to step 4:
68 can be fit into 554 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 544 from 554 leaves us with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 68

Going ahead to step 5:
When dividing 108 by 68, we get 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 981.0
If we subtract 68 from 108, we get 40.
Fetch the next digit (6) from the dividend, attach it to 40 and continue: 406 / 68

On to step 6:
The number 68 fits into 406 5 times, leaving a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 9815.0
Deduct 340 from 406 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
The number 68 fits into 660 9 times, leaving a remainder of 48.
Use 9 as the next digit of our solution. 
Result so far: 9815.9
Subtracting 612 from 660 leaves us 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.

Let's proceed to step 8:
When dividing 480 by 68, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 9815.97
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.

On to step 9:
68 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9815.97
Subtracting 0 from 40 leaves us 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.

Going ahead to step 10:
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: 9815.9705
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.

Moving on to step 11:
When dividing 600 by 68, we get 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 9815.97058
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 12:
The number 68 fits into 560 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 9815.970588
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.

Our division results in 9815.970588 with a remaining 1.6e-06.
