Let's divide 661398 by 34
We want to divide 661398 by 34.

Step 1:
The number 34 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 34

Moving on to step 2:
34 can be fit into 66 1 times, resulting in a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 32 after subtracting 34 from 66.
Append the next digit (1) from the dividend to 32 and continue with: 321 / 34

Let's proceed to step 3:
321 divided by 34 is 9 with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 306 from 321, we get 15.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 34

Moving on to step 4:
If we divide 153 by 34, we get 4 and a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Deduct 136 from 153 and we're left with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 34

Step 5:
The number 34 fits into 179 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 1945.0
Subtract 170 from 179 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 34

Going ahead to step 6:
34 goes into 98 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 19452.0
The remainder is 30 after subtracting 68 from 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
34 goes into 300 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 19452.8
If we take 272 away from 300, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
34 can be fit into 280 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 19452.88
Subtract 272 from 280 to get 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 19452.88 with a remainder of 0.008.
