Let's divide 810573 by 5
We want to figure out the number of times 810573 can be divided by 5.

Advancing to step 1:
The number 5 fits into 8 1 times, leaving 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 (1) from the dividend, attach it to 3 and continue: 31 / 5

On to step 2:
31 divided by 5 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 30 from 31 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 5

Moving on to step 3:
When dividing 10 by 5, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 162.0
Deduct 10 from 10 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 5

Let's proceed to step 4:
If we divide 5 by 5, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1621.0
If we subtract 5 from 5, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 5

Advancing to step 5:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 16211.0
Subtracting 5 from 7 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 5

Going ahead to step 6:
5 goes into 23 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 162114.0
Subtracting 20 from 23 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
5 can be fit into 30 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 162114.6
The remainder is 0 after subtracting 30 from 30.
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:
0 divided by 5 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 162114.6
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.

Let's proceed to step 9:
5 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 162114.6
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.

After the division, we end up with 162114.6 and a remainder of 0.0.
