642420 divided by 10 
Our goal is to divide 642420 by 10.

Let's proceed to step 1:
The number 10 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 10

Step 2:
10 goes into 64 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 60 from 64 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 10

Going ahead to step 3:
42 divided by 10 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 40 from 42, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 10

Let's proceed to step 4:
10 goes into 24 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 642.0
If we subtract 20 from 24, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 10

Advancing to step 5:
The number 10 fits into 42 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 6424.0
If we take 40 away from 42, we end up with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 10

Moving on to step 6:
The number 10 fits into 20 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 64242.0
Subtracting 20 from 20 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.

Step 7:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 64242.0
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.

On to step 8:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64242.0
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 result is 64242.0 with a remainder of 0.0.
