We look at the division of 644196 by 17 
We want to figure out the number of times 644196 can be divided by 17.

On to step 1:
17 can be fit into 6 0 times, resulting in 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.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 17

Advancing 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
Subtracting 51 from 64 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 17

On to step 3:
When dividing 134 by 17, we get 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 15 after subtracting 119 from 134.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 17

Step 4:
The number 17 fits into 151 8 times, leaving a remainder of 15.
The next digit of our result is 8. 
Result so far: 378.0
If we take 136 away from 151, we end up with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 17

Going ahead to step 5:
If we divide 159 by 17, we get 9 and a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 3789.0
Subtracting 153 from 159 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 17

Going ahead to step 6:
66 divided by 17 is 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 37893.0
If we take 51 away from 66, 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.

Advancing to step 7:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 37893.8
The remainder is 14 after subtracting 136 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
When dividing 140 by 17, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 37893.88
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.

After the division, we end up with 37893.88 and a remainder of 0.004.
