Let's divide 342721 by 17
We're looking to find how many times 17 goes into 342721.

Let's proceed to step 1:
17 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 17

Let's proceed to step 2:
17 can be fit into 34 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 34 from 34.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 17

Step 3:
If we divide 2 by 17, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 17

Let's proceed to step 4:
17 can be fit into 27 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 201.0
Deduct 17 from 27 and we're left with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 17

Advancing to step 5:
17 goes into 102 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 2016.0
Subtract 102 from 102 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 17

Step 6:
17 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20160.0
Subtract 0 from 1 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.

Step 7:
If we divide 10 by 17, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 20160.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to 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: 20160.05
Deduct 85 from 100 and we're left 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:
150 divided by 17 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 20160.058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 20160.0588
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 20160.0588 and a remainder of 4e-05.
