Let's divide 68086551 by 68
The aim is to understand the frequency of 68 in 68086551.

On to step 1:
The number 68 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 68

Moving on to step 2:
The number 68 fits into 68 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 68 from 68 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 68

Step 3:
When dividing 0 by 68, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 68

Advancing to step 4:
68 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 68

Moving on to step 5:
When dividing 86 by 68, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1001.0
If we take 68 away from 86, we end up with 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 68

Step 6:
If we divide 185 by 68, we get 2 and a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 10012.0
If we subtract 136 from 185, we get 49.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 68

Going ahead to step 7:
The number 68 fits into 495 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 100127.0
If we subtract 476 from 495, we get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 68

Let's proceed to step 8:
If we divide 191 by 68, we get 2 and a remainder of 55.
The next digit of our result is 2. 
Result so far: 1001272.0
If we subtract 136 from 191, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 9:
68 goes into 550 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1001272.8
If we subtract 544 from 550, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
68 goes into 60 0 times with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 1001272.8
Subtract 0 from 60 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 11:
68 can be fit into 600 8 times, resulting in a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 1001272.808
The remainder is 56 after subtracting 544 from 600.
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 12:
68 goes into 560 8 times with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1001272.8088
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 1001272.8088 with a remainder of 0.00016.
