We divide 556430 by 10
We want to figure out the number of times 556430 can be divided by 10.

On to step 1:
If we divide 5 by 10, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 10

Step 2:
10 can be fit into 55 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 50 from 55 to get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 10

Going ahead to step 3:
10 goes into 56 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Deduct 50 from 56 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 10

Let's proceed to step 4:
The number 10 fits into 64 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 556.0
Deduct 60 from 64 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 10

On to step 5:
10 goes into 43 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 5564.0
The remainder is 3 after subtracting 40 from 43.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 10

Moving on to step 6:
10 can be fit into 30 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 55643.0
Subtract 30 from 30 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.

On to step 7:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 55643.0
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.

Going ahead to step 8:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 55643.0
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.

Our division results in 55643.0 with a remaining 0.0.
