We're dividing 339894 by 10 
We're looking to find how many times 10 goes into 339894.

Going ahead to step 1:
When dividing 3 by 10, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 10

Going ahead to step 2:
The number 10 fits into 33 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 30 from 33, we get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 10

On to step 3:
When dividing 39 by 10, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 30 from 39, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 10

Step 4:
98 divided by 10 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 339.0
If we take 90 away from 98, we end up with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 10

Step 5:
10 can be fit into 89 8 times, resulting in a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 3398.0
If we take 80 away from 89, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 10

On to step 6:
When dividing 94 by 10, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 33989.0
Deduct 90 from 94 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
When dividing 40 by 10, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 33989.4
Deduct 40 from 40 and we're left 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.

Let's proceed to step 8:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33989.4
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.

Moving on to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33989.4
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.

The quotient of the division is 33989.4, and the remainder is 0.0.
