233979 ÷ 17 
Our goal is to divide 233979 by 17.

Step 1:
17 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 17

Moving on to step 2:
17 goes into 23 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 17 from 23 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 17

Let's proceed to step 3:
17 can be fit into 63 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 12 after subtracting 51 from 63.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 17

Advancing to step 4:
The number 17 fits into 129 7 times, leaving a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Subtracting 119 from 129 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 17

On to step 5:
17 can be fit into 107 6 times, resulting in a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 1376.0
If we take 102 away from 107, we end up with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 17

Moving on to step 6:
17 goes into 59 3 times with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 13763.0
Subtract 51 from 59 to 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.

Going ahead to step 7:
If we divide 80 by 17, we get 4 and a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 13763.4
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.

Step 8:
17 goes into 120 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 13763.47
If we subtract 119 from 120, we 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.

On to step 9:
17 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13763.47
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.

On to step 10:
When dividing 100 by 17, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 13763.4705
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.

Let's proceed to step 11:
17 can be fit into 150 8 times, resulting in a remainder of 14.
Use 8 as the next digit of our solution. 
Result so far: 13763.47058
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 12:
17 can be fit into 140 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 13763.470588
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 outcome is 13763.470588, with a leftover of 4e-07.
