We look at the division of 402385 by 17 
Our goal is to divide 402385 by 17.

Step 1:
17 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 17

Advancing to step 2:
If we divide 40 by 17, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 34 from 40, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 17

Step 3:
17 can be fit into 62 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we take 51 away from 62, we end up with 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 17

Moving on to step 4:
When dividing 113 by 17, we get 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 236.0
The remainder is 11 after subtracting 102 from 113.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 17

On to step 5:
17 goes into 118 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 2366.0
Subtract 102 from 118 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 17

Advancing to step 6:
17 goes into 165 9 times with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 23669.0
If we subtract 153 from 165, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
If we divide 120 by 17, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 23669.7
Deduct 119 from 120 and we're left 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 8:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 23669.7
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
100 divided by 17 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 23669.705
Subtract 85 from 100 to 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.

Step 10:
17 goes into 150 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 23669.7058
Subtracting 136 from 150 leaves us 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.

Step 11:
The number 17 fits into 140 8 times, leaving a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 23669.70588
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 23669.70588 with a remaining 4e-06.
