We're dividing 393859 by 34 
We want to divide 393859 by 34.

Step 1:
If we divide 3 by 34, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 34

Let's proceed to step 2:
If we divide 39 by 34, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 34 from 39 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 34

Going ahead to step 3:
34 goes into 53 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 34 from 53, we get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 34

Let's proceed to step 4:
34 can be fit into 198 5 times, resulting in a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 115.0
The remainder is 28 after subtracting 170 from 198.
Bring next digit (5) of the dividend behind the 28 and repeat the process: 285 / 34

On to step 5:
34 can be fit into 285 8 times, resulting in a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 1158.0
If we take 272 away from 285, we end up with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 34

Step 6:
If we divide 139 by 34, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 11584.0
Subtracting 136 from 139 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 34 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 11584.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 34, we get 8 with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 11584.08
If we subtract 272 from 300, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 9:
If we divide 280 by 34, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11584.088
Deduct 272 from 280 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 11584.088 and a remainder of 0.0008.
