99663 ÷ 56 
Our goal is to divide 99663 by 56.

Let's proceed to step 1:
56 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 56

Step 2:
If we divide 99 by 56, we get 1 and a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 56 from 99, we get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 56

Advancing to step 3:
56 goes into 436 7 times with a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 392 from 436 leaves us with 44.
Include the next digit (6) from the dividend after 44, then repeat: 446 / 56

On to step 4:
If we divide 446 by 56, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Subtract 392 from 446 to get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 56

Let's proceed to step 5:
The number 56 fits into 543 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 1779.0
Deduct 504 from 543 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 6:
The number 56 fits into 390 6 times, leaving a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 1779.6
If we take 336 away from 390, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
The number 56 fits into 540 9 times, leaving a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 1779.69
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
360 divided by 56 is 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1779.696
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
The number 56 fits into 240 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1779.6964
Subtract 224 from 240 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.

On to step 10:
56 can be fit into 160 2 times, resulting in a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 1779.69642
If we subtract 112 from 160, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 11:
56 goes into 480 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 1779.696428
Deduct 448 from 480 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
56 can be fit into 320 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 1779.6964285
Deduct 280 from 320 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
400 divided by 56 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 1779.69642857
Deduct 392 from 400 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 1779.69642857 with a remaining 8e-09.
