644442 divided by 17 
We want to figure out the number of times 644442 can be divided by 17.

Going ahead to step 1:
6 divided by 17 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 17

Going ahead to step 2:
17 goes into 64 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 51 from 64 to get 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 17

Step 3:
If we divide 134 by 17, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 119 from 134 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 17

On to step 4:
If we divide 154 by 17, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 379.0
Deduct 153 from 154 and we're left with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 17

Going ahead to step 5:
17 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 3790.0
The remainder is 14 after subtracting 0 from 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 17

Let's proceed to step 6:
When dividing 142 by 17, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 37908.0
Subtract 136 from 142 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.

On to step 7:
17 can be fit into 60 3 times, resulting in a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 37908.3
Subtract 51 from 60 to 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.

Moving on to step 8:
If we divide 90 by 17, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 37908.35
Subtracting 85 from 90 leaves us 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.

Moving on to step 9:
When dividing 50 by 17, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 37908.352
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.

Step 10:
160 divided by 17 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 37908.3529
Deduct 153 from 160 and we're left 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.

Advancing to step 11:
17 can be fit into 70 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 37908.35294
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.

On to step 12:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 37908.352941
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.

On to step 13:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 37908.3529411
Subtracting 17 from 30 leaves us 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.

After the division, we end up with 37908.3529411 and a remainder of 1.3e-07.
