We divide 84646144 by 5
The aim is to understand the frequency of 5 in 84646144.

Advancing to step 1:
5 can be fit into 8 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 5 from 8 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 5

Step 2:
The number 5 fits into 34 6 times, leaving a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 30 away from 34, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 5

Step 3:
5 goes into 46 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
If we take 45 away from 46, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 5

Let's proceed to step 4:
5 goes into 14 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 1692.0
The remainder is 4 after subtracting 10 from 14.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 5

Advancing to step 5:
5 can be fit into 46 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 16929.0
The remainder is 1 after subtracting 45 from 46.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 5

Moving on to step 6:
When dividing 11 by 5, we get 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 169292.0
Subtracting 10 from 11 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 5

Advancing to step 7:
The number 5 fits into 14 2 times, leaving a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1692922.0
Deduct 10 from 14 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 5

Moving on to step 8:
When dividing 44 by 5, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 16929228.0
Deduct 40 from 44 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 5 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 16929228.8
If we subtract 40 from 40, 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.

Advancing to step 10:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 16929228.8
If we subtract 0 from 0, 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.

Let's proceed to step 11:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 16929228.8
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.

After the division, we end up with 16929228.8 and a remainder of 0.0.
