We're dividing 17320158 by 663 
We want to divide 17320158 by 663.

Moving on to step 1:
1 divided by 663 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 663

Let's proceed to step 2:
663 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 663

Going ahead to step 3:
663 goes into 173 0 times with a remainder of 173.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 173 to get 173.
Take the next digit (2) from the dividend and append it to 173, then repeat: 1732 / 663

Advancing to step 4:
The number 663 fits into 1732 2 times, leaving a remainder of 406.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 1326 from 1732 leaves us with 406.
Fetch the next digit (0) from the dividend, attach it to 406 and continue: 4060 / 663

Moving on to step 5:
663 goes into 4060 6 times with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 3978 away from 4060, we end up with 82.
Take the next digit (1) from the dividend and append it to 82, then repeat: 821 / 663

Step 6:
The number 663 fits into 821 1 times, leaving a remainder of 158.
Use 1 as the next digit of our solution. 
Result so far: 261.0
If we subtract 663 from 821, we get 158.
Take the next digit (5) from the dividend and append it to 158, then repeat: 1585 / 663

Going ahead to step 7:
663 can be fit into 1585 2 times, resulting in a remainder of 259.
Record the quotient 2 as the next digit in the result. 
Result so far: 2612.0
Subtract 1326 from 1585 to get 259.
Append the next digit (8) from the dividend to 259 and continue with: 2598 / 663

Advancing to step 8:
When dividing 2598 by 663, we get 3 with a remainder of 609.
Put 3 as the next digit of the answer. 
Result so far: 26123.0
If we take 1989 away from 2598, we end up with 609.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Advancing to step 9:
If we divide 6090 by 663, we get 9 and a remainder of 123.
Write down 9 as next digit of the result. 
Result so far: 26123.9
The remainder is 123 after subtracting 5967 from 6090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 10:
When dividing 1230 by 663, we get 1 with a remainder of 567.
The number 1 becomes the next digit in our result. 
Result so far: 26123.91
Subtracting 663 from 1230 leaves us with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

Step 11:
When dividing 5670 by 663, we get 8 with a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 26123.918
Deduct 5304 from 5670 and we're left with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Moving on to step 12:
3660 divided by 663 is 5 with a remainder of 345.
Write down 5 as next digit of the result. 
Result so far: 26123.9185
If we subtract 3315 from 3660, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 13:
When dividing 3450 by 663, we get 5 with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 26123.91855
Deduct 3315 from 3450 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 26123.91855 with a remainder of 0.000135.
