669354 ÷ 17 
Let's see how many times 17 fits into 669354.

Advancing to step 1:
17 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 17

Step 2:
17 can be fit into 66 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 51 away from 66, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 17

Let's proceed to step 3:
17 goes into 159 9 times with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
Subtract 153 from 159 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 17

Moving on to step 4:
17 goes into 63 3 times with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Subtract 51 from 63 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 17

Advancing to step 5:
If we divide 125 by 17, we get 7 and a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 3937.0
The remainder is 6 after subtracting 119 from 125.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 17

Moving on to step 6:
If we divide 64 by 17, we get 3 and a remainder of 13.
The next digit of our result is 3. 
Result so far: 39373.0
If we take 51 away from 64, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 17 is 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 39373.7
If we subtract 119 from 130, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
17 can be fit into 110 6 times, resulting in a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 39373.76
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
17 can be fit into 80 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 39373.764
If we take 68 away from 80, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 17, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 39373.7647
If we subtract 119 from 120, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
When dividing 10 by 17, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 39373.7647
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 17, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 39373.764705
If we take 85 away from 100, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
If we divide 150 by 17, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 39373.7647058
Subtracting 136 from 150 leaves us 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.

Let's proceed to step 14:
140 divided by 17 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 39373.76470588
If we subtract 136 from 140, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 39373.76470588, with a leftover of 4e-09.
