12949863 ÷ 552 
Let's see how many times 552 fits into 12949863.

Moving on to step 1:
1 divided by 552 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 (2) from the dividend after 1, then repeat: 12 / 552

Going ahead to step 2:
552 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 552

On to step 3:
The number 552 fits into 129 0 times, leaving a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Take the next digit (4) from the dividend and append it to 129, then repeat: 1294 / 552

Advancing to step 4:
1294 divided by 552 is 2 with a remainder of 190.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 190 after subtracting 1104 from 1294.
Include the next digit (9) from the dividend after 190, then repeat: 1909 / 552

Advancing to step 5:
The number 552 fits into 1909 3 times, leaving a remainder of 253.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we take 1656 away from 1909, we end up with 253.
Bring next digit (8) of the dividend behind the 253 and repeat the process: 2538 / 552

Moving on to step 6:
When dividing 2538 by 552, we get 4 with a remainder of 330.
Write down 4 as next digit of the result. 
Result so far: 234.0
Deduct 2208 from 2538 and we're left with 330.
Bring next digit (6) of the dividend behind the 330 and repeat the process: 3306 / 552

Moving on to step 7:
3306 divided by 552 is 5 with a remainder of 546.
The number 5 becomes the next digit in our result. 
Result so far: 2345.0
If we subtract 2760 from 3306, we get 546.
Grab the next digit (3) from the dividend, add it to 546, then carry on: 5463 / 552

Let's proceed to step 8:
The number 552 fits into 5463 9 times, leaving a remainder of 495.
The number 9 becomes the next digit in our result. 
Result so far: 23459.0
If we subtract 4968 from 5463, we get 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Let's proceed to step 9:
If we divide 4950 by 552, we get 8 and a remainder of 534.
Put 8 as the next digit of the answer. 
Result so far: 23459.8
If we subtract 4416 from 4950, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

On to step 10:
552 can be fit into 5340 9 times, resulting in a remainder of 372.
Record the quotient 9 as the next digit in the result. 
Result so far: 23459.89
If we subtract 4968 from 5340, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Moving on to step 11:
If we divide 3720 by 552, we get 6 and a remainder of 408.
Write down 6 as next digit of the result. 
Result so far: 23459.896
If we take 3312 away from 3720, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 12:
552 goes into 4080 7 times with a remainder of 216.
Put 7 as the next digit of the answer. 
Result so far: 23459.8967
Subtract 3864 from 4080 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 13:
If we divide 2160 by 552, we get 3 and a remainder of 504.
Record the quotient 3 as the next digit in the result. 
Result so far: 23459.89673
If we subtract 1656 from 2160, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 14:
5040 divided by 552 is 9 with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 23459.896739
If we take 4968 away from 5040, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 15:
552 can be fit into 720 1 times, resulting in a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 23459.8967391
Subtracting 552 from 720 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 16:
The number 552 fits into 1680 3 times, leaving a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 23459.89673913
Deduct 1656 from 1680 and we're left 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.

The quotient of the division is 23459.89673913, and the remainder is 2.4e-08.
