We look at the division of 17563940 by 663 
Let's see how many times 663 fits into 17563940.

Let's proceed to step 1:
The number 663 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 663

Step 2:
663 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 663

Moving on to step 3:
The number 663 fits into 175 0 times, leaving a remainder of 175.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 175 after subtracting 0 from 175.
Bring next digit (6) of the dividend behind the 175 and repeat the process: 1756 / 663

On to step 4:
663 goes into 1756 2 times with a remainder of 430.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 1326 from 1756 and we're left with 430.
Grab the next digit (3) from the dividend, add it to 430, then carry on: 4303 / 663

Advancing to step 5:
When dividing 4303 by 663, we get 6 with a remainder of 325.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we subtract 3978 from 4303, we get 325.
Append the next digit (9) from the dividend to 325 and continue with: 3259 / 663

Moving on to step 6:
If we divide 3259 by 663, we get 4 and a remainder of 607.
Use 4 as the next digit of our solution. 
Result so far: 264.0
Subtract 2652 from 3259 to get 607.
Bring next digit (4) of the dividend behind the 607 and repeat the process: 6074 / 663

On to step 7:
The number 663 fits into 6074 9 times, leaving a remainder of 107.
The next digit of our result is 9. 
Result so far: 2649.0
Subtract 5967 from 6074 to get 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 663

Advancing to step 8:
The number 663 fits into 1070 1 times, leaving a remainder of 407.
Record the quotient 1 as the next digit in the result. 
Result so far: 26491.0
Deduct 663 from 1070 and we're left with 407.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Going ahead to step 9:
663 can be fit into 4070 6 times, resulting in a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 26491.6
Subtracting 3978 from 4070 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 10:
If we divide 920 by 663, we get 1 and a remainder of 257.
The number 1 becomes the next digit in our result. 
Result so far: 26491.61
Deduct 663 from 920 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 11:
If we divide 2570 by 663, we get 3 and a remainder of 581.
The number 3 becomes the next digit in our result. 
Result so far: 26491.613
If we subtract 1989 from 2570, we get 581.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Step 12:
When dividing 5810 by 663, we get 8 with a remainder of 506.
Put 8 as the next digit of the answer. 
Result so far: 26491.6138
If we subtract 5304 from 5810, we get 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 13:
663 goes into 5060 7 times with a remainder of 419.
The number 7 becomes the next digit in our result. 
Result so far: 26491.61387
The remainder is 419 after subtracting 4641 from 5060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 14:
When dividing 4190 by 663, we get 6 with a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 26491.613876
Subtracting 3978 from 4190 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
The number 663 fits into 2120 3 times, leaving a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 26491.6138763
Subtracting 1989 from 2120 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 16:
663 goes into 1310 1 times with a remainder of 647.
The number 1 becomes the next digit in our result. 
Result so far: 26491.61387631
Subtract 663 from 1310 to get 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

The final result is 26491.61387631 with a remainder of 6.47e-07.
