Let's divide 203510 by 17
We want to figure out the number of times 203510 can be divided by 17.

Going ahead to step 1:
2 divided by 17 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 17

On to step 2:
17 goes into 20 1 times with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 17 from 20, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 17

Moving on to step 3:
33 divided by 17 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 17 from 33 and we're left with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 17

Let's proceed to step 4:
When dividing 165 by 17, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Deduct 153 from 165 and we're left with 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 17

Step 5:
17 goes into 121 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 1197.0
Subtracting 119 from 121 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 17

Step 6:
When dividing 20 by 17, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 11971.0
If we subtract 17 from 20, we 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.

Let's proceed to step 7:
17 can be fit into 30 1 times, resulting in a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 11971.1
The remainder is 13 after subtracting 17 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 8:
When dividing 130 by 17, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 11971.17
Deduct 119 from 130 and we're left with 11.
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 9:
When dividing 110 by 17, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11971.176
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 10:
17 can be fit into 80 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 11971.1764
The remainder is 12 after subtracting 68 from 80.
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 11:
If we divide 120 by 17, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 11971.17647
Subtracting 119 from 120 leaves us 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.

Step 12:
10 divided by 17 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11971.17647
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.

Moving on to step 13:
If we divide 100 by 17, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 11971.1764705
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 14:
150 divided by 17 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 11971.17647058
If we take 136 away from 150, we end up 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.

The final outcome is 11971.17647058, with a leftover of 1.4e-08.
