210826 divided by 5 
The aim is to understand the frequency of 5 in 210826.

Advancing to step 1:
The number 5 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 5

Going ahead to step 2:
If we divide 21 by 5, we get 4 and a remainder of 1.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 20 from 21, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 5

Moving on to step 3:
10 divided by 5 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 10 from 10 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 5

Moving on to step 4:
8 divided by 5 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 421.0
The remainder is 3 after subtracting 5 from 8.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 5

Advancing to step 5:
The number 5 fits into 32 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 4216.0
Subtract 30 from 32 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 5

Step 6:
When dividing 26 by 5, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 42165.0
The remainder is 1 after subtracting 25 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 5, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 42165.2
If we subtract 10 from 10, we 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.

On to step 8:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 42165.2
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.

Going ahead to step 9:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42165.2
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.

The final outcome is 42165.2, with a leftover of 0.0.
