We're dividing 402970 by 17 
We want to divide 402970 by 17.

Going ahead to step 1:
17 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 17

Let's proceed to step 2:
If we divide 40 by 17, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
If we take 34 away from 40, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 17

Let's proceed to step 3:
17 can be fit into 62 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 51 away from 62, we end up with 11.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 17

Advancing to step 4:
17 goes into 119 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 237.0
If we take 119 away from 119, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 17

Going ahead to step 5:
17 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 2370.0
If we subtract 0 from 7, we get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 17

Step 6:
17 goes into 70 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 23704.0
If we subtract 68 from 70, we 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 7:
17 goes into 20 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 23704.1
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.

Going ahead to step 8:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 23704.11
If we subtract 17 from 30, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 23704.11 with a remaining 0.013.
