We're dividing 640180 by 17 
We want to figure out the number of times 640180 can be divided by 17.

Going ahead to step 1:
If we divide 6 by 17, we get 0 and 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.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 17

Advancing to step 2:
When dividing 64 by 17, we get 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 51 from 64, we get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 17

Advancing to step 3:
When dividing 130 by 17, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 119 from 130, we get 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 17

Advancing to step 4:
111 divided by 17 is 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 376.0
The remainder is 9 after subtracting 102 from 111.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 17

Going ahead to step 5:
17 can be fit into 98 5 times, resulting in a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 3765.0
If we take 85 away from 98, we end up with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 17

Going ahead to step 6:
If we divide 130 by 17, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 37657.0
The remainder is 11 after subtracting 119 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
The number 17 fits into 110 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 37657.6
If we subtract 102 from 110, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 17 fits into 80 4 times, leaving a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 37657.64
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
120 divided by 17 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 37657.647
If we take 119 away from 120, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
10 divided by 17 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 37657.647
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
17 goes into 100 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 37657.64705
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
150 divided by 17 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 37657.647058
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.

On to step 13:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 37657.6470588
Subtract 136 from 140 to 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 37657.6470588 and a remainder of 4e-08.
