216003 divided by 17 
We want to figure out the number of times 216003 can be divided by 17.

Going ahead to step 1:
17 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 17

On to step 2:
17 can be fit into 21 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 17 from 21 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 17

Advancing to step 3:
When dividing 46 by 17, we get 2 with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 34 from 46 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 17

Let's proceed to step 4:
120 divided by 17 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we subtract 119 from 120, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 17

On to step 5:
When dividing 10 by 17, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1270.0
Deduct 0 from 10 and we're left with 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 17

On to step 6:
103 divided by 17 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 12706.0
Subtract 102 from 103 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.

Advancing to step 7:
When dividing 10 by 17, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 12706.0
If we subtract 0 from 10, we 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.

Step 8:
100 divided by 17 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12706.05
If we subtract 85 from 100, we 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.

Advancing to step 9:
When dividing 150 by 17, we get 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 12706.058
Subtract 136 from 150 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 10:
When dividing 140 by 17, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 12706.0588
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.

The final result is 12706.0588 with a remainder of 4e-05.
