67018088 divided by 5 
The aim is to understand the frequency of 5 in 67018088.

Step 1:
If we divide 6 by 5, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 5 from 6 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 5

Going ahead to step 2:
When dividing 17 by 5, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 15 from 17, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

Advancing to step 3:
20 divided by 5 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 20 from 20 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Moving on to step 4:
1 divided by 5 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 1340.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 5

Going ahead to step 5:
5 goes into 18 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13403.0
The remainder is 3 after subtracting 15 from 18.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 5

Moving on to step 6:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 134036.0
If we take 30 away from 30, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 5

Advancing to step 7:
8 divided by 5 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1340361.0
If we take 5 away from 8, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 5

Let's proceed to step 8:
The number 5 fits into 38 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 13403617.0
Subtract 35 from 38 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
5 goes into 30 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 13403617.6
If we take 30 away from 30, 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:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13403617.6
Subtracting 0 from 0 leaves us 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.

Step 11:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13403617.6
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.

The final result is 13403617.6 with a remainder of 0.0.
