We divide 728858 by 78
The aim is to understand the frequency of 78 in 728858.

Moving on to step 1:
When dividing 7 by 78, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 78

Step 2:
72 divided by 78 is 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (8) from the dividend to 72 and continue with: 728 / 78

Step 3:
The number 78 fits into 728 9 times, leaving a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 702 from 728 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 78

Advancing to step 4:
268 divided by 78 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 34 after subtracting 234 from 268.
Grab the next digit (5) from the dividend, add it to 34, then carry on: 345 / 78

Let's proceed to step 5:
If we divide 345 by 78, we get 4 and a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 934.0
Subtract 312 from 345 to get 33.
Take the next digit (8) from the dividend and append it to 33, then repeat: 338 / 78

On to step 6:
338 divided by 78 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 9344.0
The remainder is 26 after subtracting 312 from 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
If we divide 260 by 78, we get 3 and a remainder of 26.
The next digit of our result is 3. 
Result so far: 9344.3
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
78 goes into 260 3 times with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 9344.33
The remainder is 26 after subtracting 234 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 9344.33 with a remaining 0.026.
