We look at the division of 70606731 by 5 
The aim is to understand the frequency of 5 in 70606731.

Going ahead to step 1:
5 goes into 7 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 5 from 7, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

Going ahead to step 2:
The number 5 fits into 20 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 20 from 20 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 5

Moving on to step 3:
The number 5 fits into 6 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
If we take 5 away from 6, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

Step 4:
The number 5 fits into 10 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 1412.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 5

Step 5:
When dividing 6 by 5, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 14121.0
If we take 5 away from 6, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 5

Step 6:
If we divide 17 by 5, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 141213.0
If we take 15 away from 17, we end up with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 5

Step 7:
When dividing 23 by 5, we get 4 with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1412134.0
If we take 20 away from 23, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 5

Going ahead to step 8:
31 divided by 5 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 14121346.0
Deduct 30 from 31 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
When dividing 10 by 5, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 14121346.2
Deduct 10 from 10 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 10:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14121346.2
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 11:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14121346.2
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.

The final result is 14121346.2 with a remainder of 0.0.
