Let's divide 688281 by 78
The aim is to understand the frequency of 78 in 688281.

Let's proceed to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 78

Going ahead to step 2:
78 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Bring next digit (8) of the dividend behind the 68 and repeat the process: 688 / 78

Step 3:
78 goes into 688 8 times with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 624 from 688 leaves us with 64.
Include the next digit (2) from the dividend after 64, then repeat: 642 / 78

Advancing to step 4:
642 divided by 78 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 88.0
If we take 624 away from 642, we end up with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 78

Step 5:
78 goes into 188 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 882.0
Subtracting 156 from 188 leaves us with 32.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 78

Going ahead to step 6:
If we divide 321 by 78, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 8824.0
The remainder is 9 after subtracting 312 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
78 can be fit into 90 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 8824.1
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 8:
120 divided by 78 is 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 8824.11
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The quotient of the division is 8824.11, and the remainder is 0.042.
