We're dividing 811187 by 5 
We're looking to find how many times 5 goes into 811187.

Step 1:
The number 5 fits into 8 1 times, leaving a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 5

Let's proceed to step 2:
If we divide 31 by 5, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtracting 30 from 31 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 5

Going ahead to step 3:
When dividing 11 by 5, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 162.0
Subtract 10 from 11 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 5

Advancing to step 4:
The number 5 fits into 11 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 1622.0
Subtracting 10 from 11 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 5

On to step 5:
The number 5 fits into 18 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 16223.0
Subtracting 15 from 18 leaves us with 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 5

Step 6:
When dividing 37 by 5, we get 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 162237.0
Subtracting 35 from 37 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.

Step 7:
5 can be fit into 20 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 162237.4
If we subtract 20 from 20, 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 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 162237.4
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.

Let's proceed to step 9:
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: 162237.4
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 outcome is 162237.4, with a leftover of 0.0.
