We're dividing 12447671 by 903 
Our goal is to divide 12447671 by 903.

Let's proceed to step 1:
1 divided by 903 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 903

Advancing to step 2:
If we divide 12 by 903, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 903

On to step 3:
If we divide 124 by 903, we get 0 and a remainder of 124.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 124 to get 124.
Take the next digit (4) from the dividend and append it to 124, then repeat: 1244 / 903

Let's proceed to step 4:
The number 903 fits into 1244 1 times, leaving a remainder of 341.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 341 after subtracting 903 from 1244.
Include the next digit (7) from the dividend after 341, then repeat: 3417 / 903

Going ahead to step 5:
3417 divided by 903 is 3 with a remainder of 708.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 2709 away from 3417, we end up with 708.
Take the next digit (6) from the dividend and append it to 708, then repeat: 7086 / 903

Let's proceed to step 6:
903 goes into 7086 7 times with a remainder of 765.
The next digit of our result is 7. 
Result so far: 137.0
Subtract 6321 from 7086 to get 765.
Append the next digit (7) from the dividend to 765 and continue with: 7657 / 903

Let's proceed to step 7:
903 can be fit into 7657 8 times, resulting in a remainder of 433.
Use 8 as the next digit of our solution. 
Result so far: 1378.0
The remainder is 433 after subtracting 7224 from 7657.
Include the next digit (1) from the dividend after 433, then repeat: 4331 / 903

Step 8:
The number 903 fits into 4331 4 times, leaving a remainder of 719.
Use 4 as the next digit of our solution. 
Result so far: 13784.0
If we take 3612 away from 4331, we end up with 719.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7190, and continue the process.

Step 9:
7190 divided by 903 is 7 with a remainder of 869.
Put 7 as the next digit of the answer. 
Result so far: 13784.7
If we subtract 6321 from 7190, we get 869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8690, and continue the process.

Moving on to step 10:
903 goes into 8690 9 times with a remainder of 563.
Use 9 as the next digit of our solution. 
Result so far: 13784.79
Subtracting 8127 from 8690 leaves us with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

On to step 11:
903 goes into 5630 6 times with a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 13784.796
If we subtract 5418 from 5630, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 12:
The number 903 fits into 2120 2 times, leaving a remainder of 314.
Write down 2 as next digit of the result. 
Result so far: 13784.7962
Subtracting 1806 from 2120 leaves us with 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

On to step 13:
903 goes into 3140 3 times with a remainder of 431.
The number 3 becomes the next digit in our result. 
Result so far: 13784.79623
Deduct 2709 from 3140 and we're left with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 14:
903 can be fit into 4310 4 times, resulting in a remainder of 698.
Write down 4 as next digit of the result. 
Result so far: 13784.796234
The remainder is 698 after subtracting 3612 from 4310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

On to step 15:
The number 903 fits into 6980 7 times, leaving a remainder of 659.
Record the quotient 7 as the next digit in the result. 
Result so far: 13784.7962347
The remainder is 659 after subtracting 6321 from 6980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Let's proceed to step 16:
6590 divided by 903 is 7 with a remainder of 269.
Use 7 as the next digit of our solution. 
Result so far: 13784.79623477
The remainder is 269 after subtracting 6321 from 6590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 13784.79623477, with a leftover of 2.69e-07.
