642009 divided by 17 
Our goal is to divide 642009 by 17.

Going ahead 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
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 17

Advancing to step 2:
If we divide 64 by 17, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 51 from 64 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 17

Advancing to step 3:
17 can be fit into 132 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 37.0
Deduct 119 from 132 and we're left with 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 17

On to step 4:
17 can be fit into 130 7 times, resulting in a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 377.0
Subtracting 119 from 130 leaves us with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 17

Moving on to step 5:
110 divided by 17 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3776.0
Subtract 102 from 110 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 17

Moving on to step 6:
The number 17 fits into 89 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 37765.0
The remainder is 4 after subtracting 85 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
17 can be fit into 40 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 37765.2
If we subtract 34 from 40, we 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.

Let's proceed to step 8:
60 divided by 17 is 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 37765.23
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 17, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 37765.235
The remainder is 5 after subtracting 85 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 17, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 37765.2352
If we subtract 34 from 50, we 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.

Moving on to step 11:
The number 17 fits into 160 9 times, leaving a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 37765.23529
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.

Moving on to step 12:
If we divide 70 by 17, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 37765.235294
Subtract 68 from 70 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 13:
If we divide 20 by 17, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 37765.2352941
Subtract 17 from 20 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
When dividing 30 by 17, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 37765.23529411
If we take 17 away from 30, 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.

The final result is 37765.23529411 with a remainder of 1.3e-08.
