We're dividing 390083 by 5 
The aim is to understand the frequency of 5 in 390083.

Step 1:
The number 5 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 5

Moving on to step 2:
The number 5 fits into 39 7 times, leaving a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 35 from 39 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

Moving on to step 3:
When dividing 40 by 5, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 40 from 40, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 5

Advancing to step 4:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 780.0
Subtract 0 from 0 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 5

Moving on to step 5:
8 divided by 5 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 7801.0
Subtracting 5 from 8 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 5

Moving on to step 6:
5 can be fit into 33 6 times, resulting in a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 78016.0
If we take 30 away from 33, we end up 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.

Step 7:
30 divided by 5 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 78016.6
Deduct 30 from 30 and we're left 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 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 78016.6
Deduct 0 from 0 and we're left 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 9:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 78016.6
Deduct 0 from 0 and we're left 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 final result is 78016.6 with a remainder of 0.0.
