We're dividing 78404 by 68 
The aim is to understand the frequency of 68 in 78404.

Advancing to step 1:
7 divided by 68 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 68

Let's proceed to step 2:
68 goes into 78 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 68 from 78 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 68

Going ahead to step 3:
68 goes into 104 1 times with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 36 after subtracting 68 from 104.
Bring next digit (0) of the dividend behind the 36 and repeat the process: 360 / 68

Advancing to step 4:
The number 68 fits into 360 5 times, leaving a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 115.0
The remainder is 20 after subtracting 340 from 360.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 68

On to step 5:
204 divided by 68 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1153.0
Subtracting 204 from 204 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 6:
68 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1153.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 68, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1153.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1153.0 with a remaining 0.0.
