We divide 801889 by 5
The aim is to understand the frequency of 5 in 801889.

Moving on to step 1:
5 can be fit into 8 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 5

Step 2:
If we divide 30 by 5, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 30 from 30, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Going ahead to step 3:
1 divided by 5 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 160.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 5

Going ahead to step 4:
18 divided by 5 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1603.0
If we take 15 away from 18, we end up with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 5

Advancing to step 5:
The number 5 fits into 38 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 16037.0
Subtract 35 from 38 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

On to step 6:
If we divide 39 by 5, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 160377.0
Subtract 35 from 39 to get 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 7:
If we divide 40 by 5, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 160377.8
Subtracting 40 from 40 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.

Moving on to step 8:
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: 160377.8
Deduct 0 from 0 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.

Let's proceed to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 160377.8
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 160377.8 and a remainder of 0.0.
