We look at the division of 88378 by 5 
The aim is to understand the frequency of 5 in 88378.

Let's proceed to step 1:
When dividing 8 by 5, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 5 from 8.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 5

Going ahead to step 2:
5 can be fit into 38 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 35 from 38, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 5

Step 3:
5 goes into 33 6 times with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 176.0
Subtracting 30 from 33 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 5

Going ahead to step 4:
5 can be fit into 37 7 times, resulting in a remainder of 2.
The next digit of our result is 7. 
Result so far: 1767.0
If we take 35 away from 37, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 5

Step 5:
5 can be fit into 28 5 times, resulting in a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 17675.0
Subtracting 25 from 28 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 6:
The number 5 fits into 30 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 17675.6
If we take 30 away from 30, we end up 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.

On to step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17675.6
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.

Advancing to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 17675.6
If we take 0 away from 0, we end up 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.

The quotient of the division is 17675.6, and the remainder is 0.0.
