We divide 78605485 by 5
The aim is to understand the frequency of 5 in 78605485.

Let's proceed to step 1:
5 can be fit into 7 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 5 from 7 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 5

Moving on to step 2:
If we divide 28 by 5, we get 5 and a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 25 from 28 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 5

Let's proceed to step 3:
If we divide 36 by 5, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 157.0
Subtracting 35 from 36 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 5

Step 4:
10 divided by 5 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1572.0
Subtract 10 from 10 to get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 5

Let's proceed to step 5:
If we divide 5 by 5, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 15721.0
Subtract 5 from 5 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 5

Moving on to step 6:
When dividing 4 by 5, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 157210.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 5

Moving on to step 7:
5 goes into 48 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1572109.0
Subtracting 45 from 48 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 5

Advancing to step 8:
The number 5 fits into 35 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 15721097.0
Deduct 35 from 35 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 9:
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: 15721097.0
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 10:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15721097.0
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.

The quotient of the division is 15721097.0, and the remainder is 0.0.
