Let's divide 85671505 by 5
The aim is to understand the frequency of 5 in 85671505.

Step 1:
8 divided by 5 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 5 from 8.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 5

Going ahead to step 2:
5 can be fit into 35 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 0 after subtracting 35 from 35.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 5

Let's proceed 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: 171.0
The remainder is 1 after subtracting 5 from 6.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 5

Step 4:
5 goes into 17 3 times with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 1713.0
The remainder is 2 after subtracting 15 from 17.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 5

Step 5:
5 can be fit into 21 4 times, resulting in a remainder of 1.
The next digit of our result is 4. 
Result so far: 17134.0
If we take 20 away from 21, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 5

Step 6:
5 goes into 15 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 171343.0
Deduct 15 from 15 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 5

On to step 7:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1713430.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 5

On to step 8:
5 divided by 5 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 17134301.0
If we take 5 away from 5, 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.

Going ahead to step 9:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 17134301.0
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.

Step 10:
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: 17134301.0
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 quotient of the division is 17134301.0, and the remainder is 0.0.
