815607 ÷ 68 
The aim is to understand the frequency of 68 in 815607.

Let's proceed to step 1:
68 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 68

Step 2:
The number 68 fits into 81 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 68 from 81, we get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 68

Let's proceed to step 3:
68 goes into 135 1 times with a remainder of 67.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 67 after subtracting 68 from 135.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 68

Going ahead to step 4:
When dividing 676 by 68, we get 9 with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 119.0
If we subtract 612 from 676, we get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 68

Advancing to step 5:
68 can be fit into 640 9 times, resulting in a remainder of 28.
The number 9 becomes the next digit in our result. 
Result so far: 1199.0
If we subtract 612 from 640, we get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 68

On to step 6:
If we divide 287 by 68, we get 4 and a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 11994.0
Subtracting 272 from 287 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
68 goes into 150 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 11994.2
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 68 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 11994.22
If we subtract 136 from 140, we 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.

The quotient of the division is 11994.22, and the remainder is 0.004.
