639206 ÷ 17 
We're looking to find how many times 17 goes into 639206.

Let's proceed to step 1:
The number 17 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
Subtract 0 from 6 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Going ahead to step 2:
17 can be fit into 63 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 51 from 63 to get 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 17

Advancing to step 3:
17 can be fit into 129 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 37.0
If we take 119 away from 129, we end up with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 17

Going ahead to step 4:
102 divided by 17 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 376.0
Subtract 102 from 102 to get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 17

Let's proceed to step 5:
The number 17 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3760.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 17

Step 6:
The number 17 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 37600.0
Subtract 0 from 6 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
When dividing 60 by 17, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 37600.3
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
When dividing 90 by 17, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 37600.35
Deduct 85 from 90 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
If we divide 50 by 17, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 37600.352
If we take 34 away from 50, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
When dividing 160 by 17, we get 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 37600.3529
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 11:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 37600.35294
If we take 68 away from 70, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 37600.352941
Deduct 17 from 20 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.

Going ahead to step 13:
30 divided by 17 is 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 37600.3529411
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 37600.3529411 with a balance of 1.3e-07.
