We divide 90212032 by 5
The aim is to understand the frequency of 5 in 90212032.

Let's proceed to step 1:
When dividing 9 by 5, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 5 from 9.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 5

Advancing to step 2:
When dividing 40 by 5, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 40 from 40, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 5

Let's proceed to step 3:
The number 5 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 180.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 5

On to step 4:
5 goes into 21 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1804.0
Subtracting 20 from 21 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 5

Step 5:
When dividing 12 by 5, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 18042.0
Subtracting 10 from 12 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

Moving on to step 6:
If we divide 20 by 5, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 180424.0
Subtracting 20 from 20 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 5

Let's proceed to step 7:
If we divide 3 by 5, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 1804240.0
If we subtract 0 from 3, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 5

On to step 8:
5 can be fit into 32 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 18042406.0
Subtracting 30 from 32 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
5 can be fit into 20 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 18042406.4
Deduct 20 from 20 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:
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: 18042406.4
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.

Step 11:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18042406.4
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.

Our division results in 18042406.4 with a remaining 0.0.
