649539 divided by 5 
The aim is to understand the frequency of 5 in 649539.

On to step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 5 away from 6, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 5

Step 2:
The number 5 fits into 14 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 10 from 14 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 5

Moving on to step 3:
When dividing 49 by 5, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 129.0
The remainder is 4 after subtracting 45 from 49.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 5

Advancing to step 4:
If we divide 45 by 5, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1299.0
The remainder is 0 after subtracting 45 from 45.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 5

On to step 5:
5 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 12990.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 5

Moving on to step 6:
5 goes into 39 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 129907.0
Deduct 35 from 39 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
5 goes into 40 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 129907.8
If we take 40 away from 40, 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.

Moving on to step 8:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129907.8
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.

Let's proceed to step 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 129907.8
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.

The final result is 129907.8 with a remainder of 0.0.
