Let's divide 439802 by 10
We want to figure out the number of times 439802 can be divided by 10.

Step 1:
If we divide 4 by 10, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 10

Step 2:
The number 10 fits into 43 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 40 away from 43, we end up with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 10

Step 3:
When dividing 39 by 10, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we subtract 30 from 39, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 10

Moving on to step 4:
When dividing 98 by 10, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 439.0
Deduct 90 from 98 and we're left with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 10

On to step 5:
10 goes into 80 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 4398.0
The remainder is 0 after subtracting 80 from 80.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 10

On to step 6:
10 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 43980.0
If we take 0 away from 2, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
10 goes into 20 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 43980.2
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.

Advancing to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43980.2
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.

Step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43980.2
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.

The final result is 43980.2 with a remainder of 0.0.
