We look at the division of 639745 by 17 
We want to figure out the number of times 639745 can be divided by 17.

Moving on to step 1:
17 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 17

On to step 2:
If we divide 63 by 17, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 12 after subtracting 51 from 63.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 17

Going ahead to step 3:
When dividing 129 by 17, we get 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 37.0
The remainder is 10 after subtracting 119 from 129.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 17

Advancing to step 4:
17 can be fit into 107 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 376.0
Subtract 102 from 107 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 17

On to step 5:
The number 17 fits into 54 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3763.0
Subtract 51 from 54 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 17

Step 6:
If we divide 35 by 17, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 37632.0
Subtract 34 from 35 to 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.

Going ahead to step 7:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 37632.0
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 8:
17 can be fit into 100 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 37632.05
Subtracting 85 from 100 leaves us 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.

Advancing to step 9:
17 can be fit into 150 8 times, resulting in a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 37632.058
If we subtract 136 from 150, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
17 goes into 140 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 37632.0588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 37632.0588 with a remaining 4e-05.
