We're dividing 35850457 by 17 
We're looking to find how many times 17 goes into 35850457.

Moving on to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 17

On to step 2:
17 can be fit into 35 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 34 from 35 and we're left with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 17

Step 3:
The number 17 fits into 18 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 17 from 18 to get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 17

Step 4:
17 goes into 15 0 times with a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 210.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 17

On to step 5:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 2108.0
If we subtract 136 from 150, we get 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 17

Moving on to step 6:
If we divide 144 by 17, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 21088.0
Deduct 136 from 144 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 17

Going ahead to step 7:
When dividing 85 by 17, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 210885.0
The remainder is 0 after subtracting 85 from 85.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 17

Advancing to step 8:
If we divide 7 by 17, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 2108850.0
Subtract 0 from 7 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
When dividing 70 by 17, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2108850.4
The remainder is 2 after subtracting 68 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 2108850.41
Subtract 17 from 20 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 2108850.411
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 2108850.411 with a remainder of 0.0013.
