21279494 ÷ 663 
Let's see how many times 663 fits into 21279494.

Moving on to step 1:
The number 663 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 663

Let's proceed to step 2:
663 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Grab the next digit (2) from the dividend, add it to 21, then carry on: 212 / 663

Let's proceed to step 3:
If we divide 212 by 663, we get 0 and a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 212 to get 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 663

Going ahead to step 4:
2127 divided by 663 is 3 with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 138 after subtracting 1989 from 2127.
Bring next digit (9) of the dividend behind the 138 and repeat the process: 1389 / 663

Step 5:
1389 divided by 663 is 2 with a remainder of 63.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 1326 from 1389 to get 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 663

On to step 6:
663 can be fit into 634 0 times, resulting in a remainder of 634.
The next digit of our result is 0. 
Result so far: 320.0
The remainder is 634 after subtracting 0 from 634.
Take the next digit (9) from the dividend and append it to 634, then repeat: 6349 / 663

Moving on to step 7:
6349 divided by 663 is 9 with a remainder of 382.
Write down 9 as next digit of the result. 
Result so far: 3209.0
If we take 5967 away from 6349, we end up with 382.
Grab the next digit (4) from the dividend, add it to 382, then carry on: 3824 / 663

Step 8:
663 goes into 3824 5 times with a remainder of 509.
Record the quotient 5 as the next digit in the result. 
Result so far: 32095.0
If we take 3315 away from 3824, we end up with 509.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5090, and continue the process.

Let's proceed to step 9:
When dividing 5090 by 663, we get 7 with a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 32095.7
If we take 4641 away from 5090, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

On to step 10:
If we divide 4490 by 663, we get 6 and a remainder of 512.
The next digit of our result is 6. 
Result so far: 32095.76
If we take 3978 away from 4490, we end up with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
If we divide 5120 by 663, we get 7 and a remainder of 479.
Put 7 as the next digit of the answer. 
Result so far: 32095.767
Subtract 4641 from 5120 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 12:
The number 663 fits into 4790 7 times, leaving a remainder of 149.
The number 7 becomes the next digit in our result. 
Result so far: 32095.7677
If we subtract 4641 from 4790, we get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 32095.7677 with a remainder of 0.00149.
