We look at the division of 66439 by 34 
Our goal is to divide 66439 by 34.

Advancing to step 1:
34 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 34

Step 2:
If we divide 66 by 34, we get 1 and a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 34 from 66 to get 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 34

On to step 3:
34 can be fit into 324 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 306 from 324 leaves us with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 34

Moving on to step 4:
The number 34 fits into 183 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Subtracting 170 from 183 leaves us with 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 34

Let's proceed to step 5:
139 divided by 34 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 1954.0
Deduct 136 from 139 and we're left 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.

Moving on to step 6:
The number 34 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1954.0
Deduct 0 from 30 and we're left with 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 7:
34 goes into 300 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 1954.08
Subtract 272 from 300 to 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.

Let's proceed to step 8:
34 goes into 280 8 times with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 1954.088
Subtracting 272 from 280 leaves us 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.

The final result is 1954.088 with a remainder of 0.0008.
