We divide 550369 by 10
We want to figure out the number of times 550369 can be divided by 10.

Going ahead to step 1:
If we divide 5 by 10, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 10

Moving on to step 2:
10 goes into 55 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 50 from 55, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 10

Moving on to step 3:
If we divide 50 by 10, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 50 from 50 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

Let's proceed to step 4:
The number 10 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 550.0
Subtract 0 from 3 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 10

Advancing to step 5:
10 goes into 36 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 5503.0
The remainder is 6 after subtracting 30 from 36.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 10

Let's proceed to step 6:
If we divide 69 by 10, we get 6 and a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 55036.0
The remainder is 9 after subtracting 60 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 10 fits into 90 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 55036.9
If we subtract 90 from 90, 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:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 55036.9
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:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 55036.9
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.

The final outcome is 55036.9, with a leftover of 0.0.
