215045 ÷ 17 
We want to figure out the number of times 215045 can be divided by 17.

Going ahead to step 1:
If we divide 2 by 17, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 17

Moving on to step 2:
The number 17 fits into 21 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 17 from 21, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 17

On to step 3:
17 can be fit into 45 2 times, resulting in a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 11 after subtracting 34 from 45.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 17

Moving on to step 4:
17 goes into 110 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 102 away from 110, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 17

Moving on to step 5:
When dividing 84 by 17, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 1264.0
Subtracting 68 from 84 leaves us with 16.
Grab the next digit (5) from the dividend, add it to 16, then carry on: 165 / 17

Let's proceed to step 6:
165 divided by 17 is 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 12649.0
If we take 153 away from 165, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 17, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 12649.7
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:
17 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12649.7
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.

Moving on to step 9:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 12649.705
Deduct 85 from 100 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
If we divide 150 by 17, we get 8 and a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 12649.7058
If we subtract 136 from 150, we 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.

On to step 11:
If we divide 140 by 17, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 12649.70588
The remainder is 4 after subtracting 136 from 140.
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 outcome is 12649.70588, with a leftover of 4e-06.
