803419 ÷ 10 
We want to figure out the number of times 803419 can be divided by 10.

Step 1:
8 divided by 10 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 10

Advancing to step 2:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 80 from 80 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 10

On to step 3:
10 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 10

Let's proceed to step 4:
10 can be fit into 34 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 803.0
Deduct 30 from 34 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 10

On to step 5:
10 can be fit into 41 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 8034.0
Subtract 40 from 41 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 10

Going ahead to step 6:
10 goes into 19 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 80341.0
Deduct 10 from 19 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
10 can be fit into 90 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 80341.9
If we take 90 away from 90, 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.

Step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 80341.9
Subtract 0 from 0 to 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:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80341.9
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.

Our division results in 80341.9 with a remaining 0.0.
