664340 ÷ 17 
Let's see how many times 17 fits into 664340.

Let's proceed to step 1:
17 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 17

Going ahead to step 2:
17 can be fit into 66 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 51 from 66 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 17

Going ahead to step 3:
The number 17 fits into 154 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 39.0
If we take 153 away from 154, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 17

Advancing to step 4:
17 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 390.0
If we subtract 0 from 13, we get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 17

Let's proceed to step 5:
If we divide 134 by 17, we get 7 and a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3907.0
Subtract 119 from 134 to get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 17

Advancing to step 6:
When dividing 150 by 17, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 39078.0
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
If we divide 140 by 17, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 39078.8
Subtracting 136 from 140 leaves us 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.

Advancing to step 8:
The number 17 fits into 40 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 39078.82
If we take 34 away from 40, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 17, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 39078.823
Deduct 51 from 60 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
If we divide 90 by 17, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39078.8235
If we subtract 85 from 90, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
17 can be fit into 50 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 39078.82352
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
17 goes into 160 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39078.823529
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 13:
If we divide 70 by 17, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 39078.8235294
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
20 divided by 17 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 39078.82352941
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 39078.82352941 with a remainder of 3e-09.
