123663 divided by 17 
Our goal is to divide 123663 by 17.

Advancing to step 1:
17 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 17

Going ahead to step 2:
12 divided by 17 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 17

Let's proceed to step 3:
17 can be fit into 123 7 times, resulting in a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 119 from 123 leaves us with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 17

Step 4:
If we divide 46 by 17, we get 2 and a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 72.0
The remainder is 12 after subtracting 34 from 46.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 17

Let's proceed to step 5:
If we divide 126 by 17, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 727.0
Deduct 119 from 126 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 17

Going ahead to step 6:
The number 17 fits into 73 4 times, leaving a remainder of 5.
The next digit of our result is 4. 
Result so far: 7274.0
Subtract 68 from 73 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
17 goes into 50 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 7274.2
Subtract 34 from 50 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
17 goes into 160 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 7274.29
If we take 153 away from 160, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
70 divided by 17 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 7274.294
Subtracting 68 from 70 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 17, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 7274.2941
The remainder is 3 after subtracting 17 from 20.
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:
If we divide 30 by 17, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 7274.29411
Deduct 17 from 30 and we're left 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 outcome is 7274.29411, with a leftover of 1.3e-05.
