We divide 136972 by 5
The aim is to understand the frequency of 5 in 136972.

Going ahead to step 1:
If we divide 1 by 5, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 5

Step 2:
The number 5 fits into 13 2 times, leaving a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 10 from 13, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 5

Moving on to step 3:
36 divided by 5 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 27.0
If we subtract 35 from 36, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 5

Advancing to step 4:
When dividing 19 by 5, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 273.0
Subtract 15 from 19 to get 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 5

On to step 5:
5 goes into 47 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 2739.0
The remainder is 2 after subtracting 45 from 47.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 5

Going ahead to step 6:
The number 5 fits into 22 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 27394.0
Subtract 20 from 22 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 5, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 27394.4
The remainder is 0 after subtracting 20 from 20.
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:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27394.4
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.

On to step 9:
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: 27394.4
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.

After the division, we end up with 27394.4 and a remainder of 0.0.
