646753 ÷ 5 
The aim is to understand the frequency of 5 in 646753.

Going ahead to step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 5

Advancing to step 2:
If we divide 14 by 5, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 10 from 14 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 5

On to step 3:
46 divided by 5 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtracting 45 from 46 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 5

Step 4:
If we divide 17 by 5, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 1293.0
Subtract 15 from 17 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 5

Moving on to step 5:
When dividing 25 by 5, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 12935.0
If we take 25 away from 25, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 5

On to step 6:
5 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 129350.0
If we take 0 away from 3, 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.

On to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 129350.6
Subtract 30 from 30 to get 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:
If we divide 0 by 5, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129350.6
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 5 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 129350.6
Subtract 0 from 0 to get 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 outcome is 129350.6, with a leftover of 0.0.
