802166 divided by 68 
The aim is to understand the frequency of 68 in 802166.

Step 1:
8 divided by 68 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 68

Step 2:
68 can be fit into 80 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 68 from 80, we get 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 68

Step 3:
If we divide 122 by 68, we get 1 and a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 68 from 122 leaves us with 54.
Fetch the next digit (1) from the dividend, attach it to 54 and continue: 541 / 68

Going ahead to step 4:
The number 68 fits into 541 7 times, leaving a remainder of 65.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 476 from 541 to get 65.
Bring next digit (6) of the dividend behind the 65 and repeat the process: 656 / 68

Moving on to step 5:
68 can be fit into 656 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 1179.0
Subtracting 612 from 656 leaves us with 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 68

Moving on to step 6:
The number 68 fits into 446 6 times, leaving a remainder of 38.
The next digit of our result is 6. 
Result so far: 11796.0
Subtracting 408 from 446 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
68 can be fit into 380 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 11796.5
Subtract 340 from 380 to 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.

Moving on to step 8:
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: 11796.55
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 11796.55, and the remainder is 0.06.
